[0048] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings for the embodiments of the present disclosure to clearly and completely describe the technical solutions of the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The components of the embodiments of the present disclosure described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0049] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0050] The term “and / or” in this document is only used to describe an association relationship, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the term “at least one” in this document means any one of multiple or any combination of at least two of multiple, for example, including at least one of A, B and C can mean including any one or more elements selected from the set consisting of A, B and C.

[0051] It is found through research that in the existing file packaging technology, a compression software is usually selected to package files into a compressed package. When a user needs to use the files in the compressed package, the compressed package needs to be decompressed to obtain the data in the compressed package. Therefore, the file reading speed of the existing file packaging technology is slow. Moreover, when data in the compressed package is updated, the compressed package cannot be deleted, which will occupy a large amount of memory space, thereby affecting the stable operation of the device.

[0052] Based on the above research, the present disclosure provides a file processing method, a file searching method, an apparatus, a computer device and a storage medium. In the embodiment of the present disclosure, firstly, a to-be-processed directory can be obtained, and each level of folder and sub-file is traversed based on the hierarchical order of the folder in the to-be-processed directory to obtain packaging information of each level of folder, and a target packaging file is generated based on the packaging information, so that in the process of searching for a target file, the file position information of the target file in the target packaging file can be searched based on the packaging information, thereby on the one hand, the multiple levels of folders can be merged through file packaging to improve the file reading speed, and on the other hand, the decompression process is omitted when searching for the target file, the occupation of the memory space is reduced, and the device can operate more stably.

[0053] In order to facilitate the understanding of the present embodiment, firstly, a file processing method disclosed by the present embodiment is introduced in detail, and the execution subject of the file processing method provided by the present embodiment is generally a computer device with certain computing capability. In some possible implementation manners, the file processing method can be realized by calling the computer readable instructions stored in the memory by the processor.

[0054] Referring to Figure 1 The method provided by the present embodiment includes steps S101-S105, wherein:

[0055] S101: obtaining a to-be-processed directory, wherein the to-be-processed directory contains at least one level of folder, and each level of folder contains at least one sub-file.

[0056] In the embodiments of the present disclosure, in the process of updating the application program contained in the terminal device, a large number of update files are generated, especially in the process of incremental update, a large number of small-size update resource packages (with a capacity of several KB to several tens of KB) are generated. Due to the influence of the memory reading mechanism, the reading speed of the system when reading these small-size update resource packages is often slower than that of large-size update resource packages (here, the large size is a resource package with a capacity of GB level). Therefore, in the embodiments of the present disclosure, the files of the multiple update resources corresponding to the application program need to be packaged to improve the reading speed of the files. Here, the incremental update is different from the full update. In the process of incremental update, only the places that need to be changed are updated, and the places that do not need to be updated or have been updated will not be repeatedly updated, for example, only the bug in the application program is repaired, and the repaired part of the update content is downloaded to the application program.

[0057] In the implementation, the to-be-processed directory can be acquired first, for example, the to-be-processed directory can be the update resource directory of the application program, the update resource directory can contain at least one hierarchical folder, each hierarchical folder contains at least one sub-file, wherein the at least one hierarchical folder can correspond to the update resource of each function in the application program, and the folder can contain the incremental update sub-file corresponding to each function in the application program.

[0058] For example, the to-be-processed directory is the update resource directory of the application program A, the update resource directory corresponds to all update resources a of the application program A, and contains the folder a1 corresponding to the function a1, and the folder contains the incremental update sub-file a1.txt of the function a1. Then, the to-be-processed directory can be represented as a / a1 / a1.txt. Here, “ / ” is a hierarchical identifier, which is used to distinguish the files at different levels under the to-be-processed directory.

[0059] S103: based on the hierarchical order of the folders in the to-be-processed directory, each hierarchical folder and the sub-file in the folder are traversed to obtain the packaging information of each hierarchical folder, wherein the packaging information is used to indicate the file attribute information and the file position information of each sub-file contained in the hierarchical folder, and the file position information is used to indicate the position of the sub-file in the target packaging file to be generated.

[0060] In the embodiments of the present disclosure, first, each hierarchical folder and the sub-file contained in the folder can be traversed based on the hierarchical order of the folders in the to-be-processed directory. Here, in the process of traversal, the file attribute information and the file position information of each hierarchical folder and the sub-file contained in the folder can be acquired, and then the packaging information of each hierarchical folder is obtained based on the file attribute information and the file position information.

[0061] Here, the file attribute information can be used to indicate the type, file name, file content, and other attributes of the folder or the sub-file. The file position information can be used to indicate the hierarchical position of the folder or the sub-file in the to-be-processed file, for example, the file position information can be used to indicate the upper-level folder containing a certain sub-file and the lower-level sub-file contained by the sub-file. It should be understood that the hierarchical position of the folder or the sub-file in the to-be-processed file can be the position of the folder or the sub-file in the target packaging file to be generated.

[0062] For example, taking folder a in the to-be-processed directory as an example, the folder a contains sub-file b1 and sub-file b2, the sub-file b1 contains sub-file c, the sub-file c contains sub-file 1.txt, and in addition, the sub-file b2 contains sub-file 2.txt, then the hierarchical order of the folder a can be a / {b1 / c / 1.txt}, {b2 / 2.txt}. Therefore, when traversing the folder a and the sub-files contained therein, the traversal can be performed based on the hierarchical order of the folder a.

[0063] Specifically, in the process of traversing based on the hierarchical order a / {b1 / c / 1.txt}, the folder a can be traversed first, and then the sub-file b1, the sub-file c, and the sub-file 1.txt are traversed respectively. Then, the sub-file b2 and the sub-file 2.txt can be traversed based on the hierarchical order {b2 / 2.txt} respectively, so as to complete the traversal of the folder a and the sub-files contained in the folder a.

[0064] S105: generating the target packaging file based on the packaging information of each hierarchical folder.

[0065] In the embodiments of the present disclosure, after the packaging information of each hierarchical folder is determined, the folders of each hierarchy can be packaged according to the determined packaging information, so as to generate the target packaging file.

[0066] Here, the packaging process can be a merging and compressing process, that is, different hierarchical folders are merged to obtain a merging result, and the merging result is compressed to obtain the target packaging file, where the target packaging file can be a compressed file. Compared with the uncompressed folder, the target packaging file in the form of a compressed file greatly reduces the occupation of memory space.

[0067] It can be known from the above description that, in the embodiment of the present disclosure, firstly, the to-be-processed directory can be acquired, and each hierarchical folder and the sub-files in the folder are traversed based on the hierarchical order of the folders in the to-be-processed directory to obtain the packaging information of each hierarchical folder, and the target packaging file is generated based on the packaging information, so that the multiple hierarchical folders are merged through file packaging, and the file reading speed is improved.

[0068] In an optional implementation, the step S103 of traversing each hierarchical folder and the sub-files in the folder based on the hierarchical order of the folders in the to-be-processed directory to obtain the packaging information of each hierarchical folder includes the following process:

[0069] S1031: determining the first packaging sub-information of each hierarchical folder based on the hierarchical order;

[0070] S1032: determining the second packaging sub-information of each sub-file contained in each hierarchical folder;

[0071] S1033: determining the packaging information of the folder based on the first packaging sub-information and the second packaging sub-information.

[0072] In the embodiment of the present disclosure, since the file attribute information and the file location information of each hierarchical folder and the sub-files contained in the folder are different, the packaging information of each hierarchical folder and the sub-files contained in the folder needs to be acquired respectively, so as to obtain the first packaging sub-information of each hierarchical folder and the second packaging sub-information of each sub-file contained in each hierarchical folder.

[0073] For example, the application program contains function A, the function A contains sub-functions B1 and B2, the update resource folder corresponding to the function A is a, the update resource folder corresponding to the sub-function B1 is b1, and the update resource folder corresponding to the sub-function B2 is b2.

[0074] Then, the folder a contains the sub-file b1 and the sub-file b2, in the process of determining the packaging information of the hierarchical folder corresponding to the folder a, firstly, the first packaging sub-information corresponding to the folder a is determined, and then the second packaging sub-information corresponding to the sub-file b1 and the sub-file b2 contained in the folder a is determined respectively.

[0075] In the embodiments of the present disclosure, in the process of determining the packing information of each hierarchical folder, the first packing sub-information of each hierarchical folder can be determined first, and the second packing sub-information of each sub-file contained in each hierarchical folder can be determined, so that the packing information of the folder is determined based on the first packing sub-information and the second packing sub-information, thereby providing a technical basis for generating a target packing file based on the packing information of each folder.

[0076] In an optional implementation, the step S1032 of determining the second packing sub-information of each sub-file contained in each hierarchical folder includes the following process:

[0077] (1) Determine the file type of each sub-file in each hierarchical folder, and determine the file packing mode matched with the file type.

[0078] (2) Determine the second packing sub-information of the sub-file based on the file packing mode.

[0079] In the embodiments of the present disclosure, since the file packing modes corresponding to different file types are different, the file type of each sub-file in each hierarchical folder needs to be determined, wherein the file type can be divided into folders and document files according to different contents contained in each sub-file.

[0080] Here, the sub-file of the file type of the folder can further contain a sub-file of a lower level, for example, the sub-file b can further contain the sub-file c. The sub-file of the file type of the document file can contain various formats of document files, for example,.txt format of document file.

[0081] After determining the file type corresponding to each sub-file of the folder, the second packing sub-information of the sub-file of the file type can be determined based on the file packing mode corresponding to different file types, wherein the second packing sub-information is used to pack the sub-file based on the file packing mode, thereby generating a target packing file.

[0082] In the embodiments of the present disclosure, since the file types of the sub-files contained in each hierarchical folder can be different, different file packing modes can be set for different types of sub-files, and the second packing sub-information of the sub-file can be obtained based on the file packing mode, thereby being applicable to packing of sub-files of different file types, and improving the accuracy of the generated target packing file.

[0083] In an optional implementation, the first packing sub-information includes at least one of the following: a type identifier of the folder, a folder name, a number of sub-files contained in the folder, a file name hash value of each sub-file in the folder, and file location information of each sub-file in the folder.

[0084] In the embodiments of the present disclosure, the type identifier of the folder can be an identifier of a file type of the folder, for example, the type identifier of the folder can be 0x2; the folder name can be a file name of the folder; the file name hash value of each sub-file in the folder can be a value obtained by calculating a hash function on the file name of the folder, which can also be referred to as a Hash value; and the file location information of each sub-file in the folder can be represented by an offset of the sub-file in the folder, where the offset can be used to represent a difference between an actual storage address of the sub-file in a storage unit and an actual storage address of the folder containing the sub-file in the storage unit, for example, the actual storage location of the folder in the storage unit is the 100th byte position, and the offset of the sub-file in the folder is 50, so the actual storage location of the sub-file in the storage unit can be the 150th byte position.

[0085] For example, the folder is a, and the folder contains a sub-file b1 and a sub-file b2, so the type identifier of the folder a can be 0x2; the folder name can be a; the number of sub-files contained in the folder can be 2; the file name hash value of each sub-file in the folder can be a file name hash value Hash(b1) of the sub-file b1 and a file name hash value Hash(b2) of the sub-file b2; and the file location information of each sub-file in the folder can be an offset (b1) of the sub-file b1 in the folder a and an offset (b2) of the sub-file b2 in the folder a.

[0086] Therefore, the first packing sub-information of the folder a can be recorded as: 0x2 | a | 2 | Hash(b1) Hash(b2) | offset(b1) offset(b2).

[0087] In the embodiments of the present disclosure, the first packing sub-information includes at least one of the following: a type identifier of the folder, a folder name, a number of sub-files contained in the folder, a file name hash value of each sub-file in the folder, and file location information of each sub-file in the folder, thereby providing a technical basis for packing the folder based on the first packing information.

[0088] In an optional embodiment, in the case that the file type of the sub-file is a folder, the second packing sub-information contains at least one of the following: type identification of the sub-file, name of the sub-file, number of sub-files contained in the sub-file, file name hash value of each sub-file in the sub-file, file location information of each sub-file in the sub-file; in the case that the file type of the sub-file is a document file, the second packing sub-information contains at least one of the following: type identification of the sub-file, name of the sub-file, length of the sub-file, content of the sub-file, file location information of the sub-file.

[0089] In the embodiments of the present disclosure, in the case that the file type of the sub-file is a folder, the second sub-information contains at least one of the following: type identification of the sub-file, name of the sub-file, number of sub-files contained in the sub-file, file name hash value of each sub-file in the sub-file, file location information of each sub-file in the sub-file, wherein the type identification of the sub-file can be 0x2.

[0090] Here, the sub-file of the file type of folder can further contain sub-files of a lower level, thus the file types of the sub-file b1, the sub-file b2 and the sub-file c of the folder a are all folders. Then, taking the sub-file b1 as an example, the type identification of the sub-file b1 is 0x2, the sub-file name is b1, the number of sub-files contained in the file is 1, the file name hash value of each sub-file in the sub-file is the file name hash value Hash(c) of the sub-file c, and the file location information of each sub-file in the sub-file is the offset (c) of the sub-file c relative to the sub-file b1. Therefore, the second packing sub-information of the sub-file b1 can be recorded as: 0x2 | b1 | 1 | Hash(c) | offset(c).

[0091] Then, by analogy, the second packing sub-information of the sub-file b2 can be recorded as: 0x2 | b2 | 1 | Hash(2.txt) | offset(2.txt); and the second packing sub-information of the sub-file c can be recorded as: 0x2 | c | 1 | Hash(1.txt) | offset(1.txt).

[0092] In the embodiments of the present disclosure, the first packing sub-information of the folder can be determined, thereby providing a technical basis for packing the folder based on the first packing sub-information.

[0093] In an optional embodiment, in the case that the file type of the sub-file is a document file, the second packing sub-information contains at least one of the following: type identification of the sub-file, name of the sub-file, length of the sub-file, content of the sub-file, file location information of the sub-file, wherein the type identification of the sub-file can be 0x1.

[0094] Here, the sub-file of the file type of document file can contain various formats of document file, so the file type of the sub-file 1.txt in the sub-file c and the sub-file 2.txt in the sub-file b2 is document file. Then, taking the sub-file 1.txt as an example, the type identifier of the sub-file 1.txt is 0x1, the sub-file name is 1.txt, the sub-file length is d(1.txt), the sub-file content is content(1.txt), and the file position information of the sub-file is the offset of the sub-file 1.txt relative to the sub-file c (offset(1.txt)). Therefore, the second packing sub-information of the sub-file 1.txt can be recorded as: 0x1 | 1.txt | d(1.txt) | content(1.txt) | offset(1.txt).

[0095] Then, by analogy, the second packing sub-information of the sub-file 2.txt can be recorded as: 0x1 | 2.txt | d(2.txt) | content(2.txt) | offset(2.txt).

[0096] In the embodiments of the present disclosure, the second packing sub-information of the sub-file of the file type of folder and document file can be determined respectively, thereby providing a technical basis for packing the sub-file based on the second packing sub-information.

[0097] In an optional implementation, the step S1032 of determining the second packing sub-information of each sub-file contained in each hierarchical folder further includes the following processes:

[0098] (1) determining the file name hash value of each sub-file;

[0099] (2) sorting each sub-file in the folder based on the file name hash value to obtain a sub-file sorting result;

[0100] (3) determining the second packing sub-information of each sub-file contained in the folder based on the sub-file sorting result.

[0101] In the embodiments of the present disclosure, the file name of each sub-file can be calculated by a hash function to obtain the file name hash value of each sub-file, and then each sub-file in the folder can be sorted based on the file name hash value to obtain a sub-file sorting result. Then, the file position information of each sub-file can be determined based on the sub-file sorting result, and the second packing sub-information of each sub-file can be determined based on the file position information.

[0102] In the embodiments of the present disclosure, after the sub-files in the folder are sorted based on the file name hash value to obtain a sub-file sorting result, each sub-file in the target packaging file generated based on the sub-file sorting result is also sorted according to the sub-file sorting result, and will not be disordered due to packaging, so that when searching for a target file in the target packaging file, the target file can be searched based on the sub-file sorting result, without decompressing the target packaging file, thereby improving the searching efficiency and saving storage space.

[0103] Referring to Figure 2 FIG. 2 shows a flowchart of a file searching method according to an embodiment of the present disclosure, and the method includes steps S201-S205, wherein:

[0104] S201: Obtain a file searching request and obtain a target searching file corresponding to the file searching request, wherein the file searching request carries a file searching path, and the target searching file is a target packaging file obtained based on the above file processing method.

[0105] In the embodiments of the present disclosure, the target file in the target searching file can be obtained through a file searching request. Here, the file searching request of the target file can be generated based on the file searching path of the target file, and the file searching path can be used to indicate the hierarchical order of the target file in the target searching file.

[0106] Here, taking the above 1.txt as an example, the file searching path corresponding to the target file can be a / b1 / c / 1.txt.

[0107] S203: Determine the file position information of each sub-file contained in each sub-path in the target searching file according to the path hierarchical order of each sub-path in the file searching path.

[0108] In the embodiments of the present disclosure, first, the packaging information of each sub-file contained in each sub-path can be determined based on the path hierarchical order of each sub-path in the above file searching path, and the file position information of the corresponding sub-file in the target searching file can be determined based on the packaging information, so as to determine the file position information of the target file.

[0109] For example, taking the file searching path a / b1 / c / 1.txt corresponding to the above target file 1.txt as an example, first, the packaging information of the folder a can be determined, and the file position information of the sub-file b1 can be determined based on the packaging information of the folder a, then the position information of the sub-file c can be determined based on the packaging information of the sub-file b1, and finally the position information of 1.txt can be determined based on the packaging information of the sub-file c.

[0110] S205: determining the target file indicated by the file search request in the target search file based on the found file location information.

[0111] In the embodiments of the present disclosure, after the file location information of the target file is determined, the target file can be searched in the target search file based on the file location information. Specifically, the file location information can be an offset (1.txt) contained in the packaging information of the target file, and the actual storage address of the target file in the storage unit can be determined based on the offset (1.txt).

[0112] As described above, in the embodiments of the present disclosure, the file location information of the target file in the target search file can be searched based on the packaging information of the target file, the process of decompressing the target search file is omitted, the occupation of the memory space is reduced, and the device can operate more stably.

[0113] In an optional implementation, the step S203 of determining the file location information of each sub-file contained in each sub-path in the target search file according to the path level order of each sub-path in the file search path specifically includes the following process:

[0114] S2031: splitting the file search path according to the path level order to obtain at least one sub-path.

[0115] In the embodiments of the present disclosure, in the process of splitting the file search path according to the path level order, the file search path can be split based on the level identifier contained in the file search path to obtain at least one sub-path. Here, the level identifier can be “ / ” as described above.

[0116] In implementation, taking the file search path a / b1 / c / 1.txt as an example, after the file search path is split based on the level identifier “ / ”, the sub-path of the folder a, the sub-path of the sub-file b1, the sub-path of the sub-file c and the sub-path of the sub-file 1.txt can be obtained respectively.

[0117] S2032: sequentially searching the hash value corresponding to each sub-path in the target search file.

[0118] S2033: in the case that the corresponding hash value is found in the target search file, searching the file location information corresponding to the sub-path in the target search file, and determining the found file location information as the file location information of the sub-file contained in the sub-path in the target search file.

[0119] In the embodiments of the present disclosure, the hash value of the next level sub-path corresponding to each sub-path can be sequentially searched according to the above path level order, and the file location information of the sub-file corresponding to the next level sub-path can be determined if the hash value of the next level sub-path is found.

[0120] In the implementation, taking the file query path a / b1 / c / 1.txt as an example, the packing information of the folder a is obtained first, and the hash value Hash(b1) of the sub-file b1 is searched in the packing information. If the hash value Hash(b1) is found, the file location information of the sub-file b1, i.e., the offset (b1), can be determined.

[0121] Next, the packing information of the sub-file b1 can be obtained, and the hash value Hash(c) of the sub-file c can be searched in the packing information. If the hash value Hash(c) is found, the file location information of the sub-file c, i.e., the offset (c), can be determined. Similarly, the file location information of the target file 1.txt, i.e., the offset (1.txt), can be determined based on the packing information of the sub-file c.

[0122] It should be noted that in the process of sequentially searching the hash value corresponding to each sub-path, a binary search method can be used. For example, the folder a corresponds to two sub-files, i.e., the sub-file b1 and the sub-file b2, the file query path corresponding to the sub-file b1 can be b1 / c / 1.txt, and the file query path corresponding to the sub-file b2 can be b2 / 2.txt. Then, the hash value Hash(c) of the sub-file c can be searched in the packing information of the sub-file b1 and the sub-file b2, respectively. As known from the above implementation, the hash value Hash(c) of the sub-file c can be found in the packing information of the sub-file b1, and the result output by the binary search for the sub-file b1 can be 1. Next, the file location information of the sub-file c can be searched in the packing information of the sub-file b1. Conversely, the result output by the binary search for the sub-file b2 can be 0.

[0123] In the embodiments of the present disclosure, the file query path can be divided into at least one sub-path according to the path level order, the hash value corresponding to each sub-path can be sequentially searched, and the file location information corresponding to the sub-path can be searched in the target file if the hash value is found, thereby improving the accuracy of searching the file location information and the response speed of the device.

[0124] To sum up, in the embodiment of the present disclosure, firstly, the to-be-processed directory can be acquired, and each hierarchical folder and sub-file is traversed based on the hierarchical order of the folders in the to-be-processed directory to obtain the packaging information of each hierarchical folder, and the target packaging file is generated based on the packaging information, so that in the process of searching for the target file, the file location information of the target file in the target packaging file can be searched based on the packaging information, thereby on the one hand, the multiple hierarchical folders can be merged through file packaging to improve the file reading speed, and on the other hand, the decompression process is omitted when searching for the target file, the memory space occupation is reduced, and the device can run more stably.
