[0002] The in-built method for data files is currently commonly applied to all electronic products equipped with Android, Android-like and Harmony systems, and is to in-build data files into the system firmware partition of the electronic product. Due to the limitation of related permissions such as reading and writing, the third-party APP cannot directly access and use the system partition, and the data files need to be copied to the internal storage area (generally, the built-in sdcard) that can be read and written after the completion of the device startup.

[0003] However, the above-mentioned method needs to perform a copy action in the system of the electronic product, and the copy not only occupies CPU and DDR resources to increase the system burden, but also increases a data space occupation, causing additional space waste, which is particularly obvious when the data file is large, thus also leading to low running efficiency of the APP. SUMMARY

[0004] In order to enable the third-party APP of the electronic product to read and write the in-built data file faster, reduce the burden of the system of the electronic product, reduce the space waste, and improve the running efficiency of the APP, the present application provides an in-built method, system, terminal and storage medium for data files.

[0044] if not, obtaining error prompt information;

[0045] if yes, proceeding to the next step.

[0046] By adopting the technical scheme, whether the verification keyword matches the verification information is judged, it can be determined whether the file data is moved to the wrong file data due to errors and the like when the file data is added to the data block file, if not matching, error prompt information is obtained for prompting, which can reduce the probability of error of the data block file, and further reduce unnecessary additional operations.

DETAILED DESCRIPTION

[0085] The following description will be made in conjunction with the accompanying drawings Figures 1 to 7 The application is further described in detail.

[0086] The embodiments of the application disclose an in-built method of data file.

[0087] Referring to Figure 1 The in-built method of data file comprises:

[0088] S1. obtaining file data of a target application;

[0089] The target application refers to a third-party APP application requiring data acquisition, and the file data refers to all data files generated in the storage system of an electronic product after the target application is run on all electronic products carrying an android, an android-like, and a Hongmeng system, and the data files include audio and video, pictures, pdf documents, database files, and all file types required by the APP. The acquisition mode can be copying from the electronic product on which the target application is installed and run.

[0090] S2. obtaining a data block file, the data block file comprising a preset format file system;

[0091] The data block file can be a pre-established data partition, and the data partition is pre-provided with a preset format file system, wherein the preset format can be an EXT4 format, and of course, in other embodiments of the application, the preset format can also be an EXT3 format or a VFAT format.

[0092] S3. adding the file data to the data block file, and obtaining a new data block file;

[0093] The specific mode can be copying the file data into the data block file, so that the data block file containing the file data is the new data block file.

[0094] S4. adding the new data block file to a preset target terminal;

[0095] The preset target terminal can be a target terminal containing a new target application but not having been started, or a terminal device not having installed the target application, i.e., about to install the target application, that is, all electronic products carrying an android, an android-like, and a Hongmeng system.

[0096] Then the data block file is added to the system of the target terminal, and the adding mode can be through the mode of flashing, the in-built system adding the new data block file to the target terminal, and of course, other modes can also be used.

[0097] S5. obtaining a data path of the new data block file in the target terminal;

[0098] When the new data block file is added to the target terminal, an independent storage area is formed, and the system can directly read the storage path formed by the file data in the storage area, that is, the data path.

[0099] S6. Obtain the read-write path of the target application of the target terminal;

[0100] When other target terminals exist and have not yet run the target application and establish a connection relationship with the built-in system, the connection relationship can be established through a data line connection, and when the target terminal is initially run, the sending port accesses the application, and the port access application includes the system directory to be accessed by the target application, that is, the read path, so that the read-write path of the target application of the target terminal can be obtained by receiving the port access application.

[0101] For example, the read-write path and the data path are stored in different drive letters, and the difference between the two is that the root directories of the drive letters are different, for example, the initial root directory of the read-write path is E, and the initial root directory of the data path is F. In addition to the difference in drive letters, the read-write path and the data path are completely the same in the E and F drives.

[0102] S7. Determine whether the read-write path is the same as the preset path;

[0103] That is, it is determined whether the path read during the startup process of the target application of the target terminal is the preset path, wherein the preset path is the path through which the target application should normally read and write data. If the read-write path is the same as the preset path, it is proved that if the target software is started at this time, data cannot be read from the new data block file.

[0104] S8. If the same, obtain a modification instruction to replace the read-write path with the data path;

[0105] S9. If different, do not obtain the modification instruction.

[0106] Therefore, if the read-write path is the same as the preset path, in order to enable the target application on the target terminal where the new data block file is stored to read the file data in the new data block file, a modification instruction, that is, a string modification instruction, is obtained at this time, so as to replace the read-write path with the data path, that is, modify the initial drive letter name of the two, so that the target application can read data according to the data path. Thus, after the target application is installed, the operation of downloading and copying file data is not required, and the required file data can be directly read, thereby improving the running efficiency of the APP, and without the need to copy files in the electronic product system, the burden of the electronic product system can be reduced, and the waste of space can be reduced. If the read-write path is different from the preset path, it is proved that the read-write path does not need to be modified, so the modification instruction does not need to be obtained.

[0107] Referring to Figure 2 In order to reduce the waste of space and facilitate access to data in the data block file, in another embodiment, obtaining the data block file comprises:

[0108] S11. Obtain a partition generation command and a file size of the file data;

[0109] The file size of the file data can be determined by identifying the attributes of the file data, and the partition generation command can be a dd command. The obtaining method can be a manual input method, or it can be automatically executed by a preset program.

[0110] S12. Generate an empty data block file based on the partition generation command and the file size;

[0111] That is, according to the dd command, an empty data space corresponding to the file size is generated in the built-in system, that is, an empty data block file.

[0112] S13. Obtain a system making command;

[0113] The system making command can be a mkfs.ext4 command, and the making instruction includes a preset format, that is, “.ext4” is the preset format. Of course, the preset format can also be an EXT3 format or a VFAT format. By using the characteristics of the ext4 file system, the data block file is an independent file system, which is convenient for access.

[0114] S14. Generate a preset format file system in the empty data block file based on the system making command;

[0115] S15. The empty data block file including the file system is taken as the data block file.

[0116] That is, the mkfs.ext4 command is used to make an ext4 format file system on the data block file, so that the empty data block file includes the file system. Therefore, the empty data block file containing the file system is the data block file.

[0117] Therefore, the empty data block file is generated based on the partition generation command and the file size, so that the size of the empty data block file can match the file size, which can reduce the waste of space, and then a preset format file system is generated, which facilitates access to data in the data block file.

[0118] Referring to Figure 3 In another embodiment, the file data is added to the data block file, and a new data block file is obtained, comprising:

[0119] S21. Obtain a mounting node;

[0120] S22. Obtain a mounting instruction to mount the data block file to a mounting node;

[0121] S23. Copy the file data to the data block file based on the corresponding mounting node, and as copy data;

[0122] S24. Obtain the permission information of the file data based on the target application;

[0123] S25. Modify the data permission of the copy data based on the permission information;

[0124] S26. The data block file with modified data permission is a new data block file.

[0125] Specifically, the mounting node can be any node in the built-in system, or a pre-set blank node, and the system can directly read. Then obtain the mounting instruction, for random mounting ground, the mounting instruction can include any node, then randomly select one, mount the data block file to the mounting node, if it is a pre-set blank node, then the mounting instruction only includes the blank node, so that the data block file is mounted to the blank node.

[0126] When the data block file is mounted to the mounting node, the system can directly read and write the file data in the data block file, and then copy the file data to the data block file according to the obtained copy instruction, and the file data copied into the data block file is as copy data.

[0127] Then obtain the permission information of the file data of the target application, wherein the permission information includes read-write permission, user group and security context, which can be obtained by reading the permission information of the file data of the target terminal running the target application.

[0128] Then modify the data permission of the copy data according to the obtained permission information, so that the permission of the copy data is the same as that of the file data, so that the data block file with modified data permission is a new data block file, so that the new target terminal can directly obtain the operation permission required by the target application when running and reading the new data block file.

[0129] Thus, according to the mounting mode, the data in the data block file can be conveniently read, and the data permission of the copy data in the data block file can be modified, so that each pre-set file can be set as a permission that can be accessed by the target application, which is more convenient.

[0130] In one embodiment of the present application, the data block file is a separate file system which can be mounted to access the data built-in, while the read-write permission, user group and security context of the last setting are retained, that is, the read-write permission, user group and security context of the target application which has been run, so that the preset file, that is, the copy file, can be set as the permission which can be accessed by the app in advance.

[0131] Referring to Figure 4 In another embodiment, adding the new data block file to the preset target terminal includes:

[0132] S13. Obtaining an uninstall instruction to uninstall the new data block file and obtaining an uninstall file;

[0133] S32. Obtaining a packaging instruction to package the uninstall file into the firmware;

[0134] S33. When the target terminal is identified, obtaining a flashing instruction to add the uninstall file in the firmware to the target terminal.

[0135] Specifically, in order to ensure the accuracy of the process of adding the data block file to the target terminal as much as possible and reduce the possibility of errors in the packaging process, after the file data is added to the new data block file, an uninstall instruction is obtained to uninstall the data block file, that is, to release the system occupation of the data block file in the system generation process, and the uninstalled new data block file is taken as an uninstall file.

[0136] Then, a packaging instruction is obtained to package the uninstall file into the firmware, so that the data in the new data block file can be copied and added to the new target terminal through the firmware. Therefore, when the system identifies the target terminal, that is, when the system establishes a communication connection relationship with the target terminal, a flashing instruction is obtained to add the uninstall file in the firmware to the target terminal.

[0137] Referring to Figure 5 In order to reduce the probability of errors of the data block file as much as possible and reduce unnecessary additional operations, in another embodiment, before obtaining the new data block file, the following steps are further included:

[0138] S41. Obtaining verification information based on the target application;

[0139] S42. Adding the verification information to the data block file;

[0140] S43. Obtaining a verification keyword of the file data when the file data is added to the data block file;

[0141] S44. Judging whether the verification keyword matches the verification information;

[0142] S45. If not matched, obtaining error prompt information;

[0143] S46. If matched, executing the step of obtaining the new data block file.

[0144] Specifically, before obtaining the new data block file, the verification information is obtained according to the target application, and the obtaining manner can be that one data keyword in the file data of the target application is obtained through a preset file obtaining path, the data keyword can represent the target application, and the data keyword is the verification information.

[0145] Then the verification information is added to the data block file in the same way as the file data is added to the data block file. Then, when the file data is added to the data block file, the verification keyword of the file data is obtained, and the obtaining manner can be that the keyword corresponding to the position of the same path as the verification information is obtained according to the path corresponding to the file data, that is, the verification keyword. Among them, the keyword can be any one of data, code, name or formula. Of course, the way to obtain the verification keyword can also be to identify all the file data, and the data at the preset position is taken as the verification keyword. When the preset position is identified, the corresponding keyword can be obtained.

[0146] Then it is judged whether the verification keyword matches the verification information, that is, whether the file data to be added to the data block file is the data required by the target application. If not matched, it proves that the copied data is different from the actual demand, which proves that it may be a misoperation that causes the data file to be copied incorrectly, so at this time, error prompt information is obtained, so as to remind the operator. The prompt manner can be through text prompt, or sound or light, etc. If matched, it proves that the data copying process is correct, so there is no need to obtain the error prompt information, so at this time, the step of obtaining the new data block file is continued.

[0147] Reference Figure 6 In order to prevent the data from being randomly copied by others as much as possible, in another embodiment, before the new data block file is added to the preset target terminal, it further comprises:

[0148] S51. Obtaining an execution password;

[0149] S52. Judging whether the execution password matches a preset password;

[0150] S53. If not matched, stopping the step of adding the new data block file to the preset target terminal;

[0151] S54. If matched, executing the step of adding the new data block file to the preset target terminal.

[0152] Specifically, that is, before adding the new data block file to the preset target terminal, an execution password is obtained, and the obtaining manner is that the system records the password of the operator. Then it is judged whether the execution password matches the preset password, and the preset password is the password that has been authorized, that is, it is judged whether the execution password is the same as the preset password. If they are the same, it proves that the operator can perform the operation step, that is, the step of adding the new data block file to the preset target terminal can be continued to be performed. If they are not the same, it proves that the execution password does not match the preset password, at which time the step of adding the new data block file to the preset target terminal is stopped, that is, the window that can continue to operate is not popped up at this time, so as to improve the security of data management as much as possible.

[0153] The implementation principle of the data file built-in method of the embodiment of the application is that: the file data is added to the data block file outside the target terminal, so as to obtain a new data block file, then the new data block file is added to the target terminal, and when the read-write path is the same as the preset path, the read-write path is replaced by the data path. The third-party APP of the electronic product can directly read and write the data file in the new data block file according to the data path, improve the running efficiency of the APP, and does not need to copy the file in the electronic product system, so as to reduce the burden of the electronic product system and reduce the waste of space.

[0154] The embodiment of the application also discloses a data file built-in system, which can achieve the same technical effects as the above-mentioned data file built-in method.

[0155] Reference Figure 7 The data file built-in system comprises:

[0156] A data acquisition module 1 is configured to acquire file data of a target application;

[0157] A first data block file acquisition module 2 is configured to acquire a data block file, and the data block file comprises a file system in a preset format;

[0158] A second data block file acquisition module 3 is configured to add the file data to the data block file and obtain a new data block file;

[0159] A data block file adding module 4 is configured to add the new data block file to a preset target terminal;

[0160] A first path acquisition module 5 is configured to acquire a data path of the new data block file in the target terminal;

[0161] A second path acquisition module 6 is configured to acquire a read-write path of the target application of the target terminal;

[0162] A path judgment module 7 is configured to judge whether the read-write path is the same as a preset path;

[0163] The path modification module 8 acquires a modification instruction to replace the read-write path with the data path if the read-write path is the same as the preset path, and does not acquire the modification instruction if the read-write path is different from the preset path.

[0164] Specifically, the data acquisition module 1 first acquires file data of a target application and sends the file data to the second data block file acquisition module 3 connected thereto. Then, the first data block file acquisition module 2 acquires a data block file and sends the data block file to the second data block file acquisition module 3 connected thereto.

[0165] Then, the second data block file acquisition module 3 adds the file data to the data block file and obtains a new data block file, and then sends the new data block file to the data block file addition module 4 connected thereto. The data block file addition module 4 adds the new data block file to a preset target terminal.

[0166] Then, the first path acquisition module 5 acquires a data path of the new data block file in the target terminal and sends the data path to the path modification module 8 connected thereto. The second path acquisition module 6 acquires a read-write path of the target application of the target terminal and sends the read-write path to the path judgment module 7 connected thereto. The path judgment module 7 judges whether the read-write path is the same as a preset path and sends the judgment result to the path modification module 8 connected thereto.

[0167] Finally, the path modification module 8 acquires a modification instruction to replace the read-write path with the data path if the read-write path is the same as the preset path, and does not acquire the modification instruction if the read-write path is different from the preset path.

[0168] Thus, the third-party APP of the electronic product can directly read and write data files in the new data block file according to the data path, improving the running efficiency of the APP, and without the need to copy files in the electronic product system, the burden of the electronic product system can be reduced, and the waste of space can be reduced.

[0169] The embodiment of the application further discloses a smart terminal including a memory and a processor. The memory stores a smart computer program.
