Embodiment Construction
[0075] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0076] like figure 1 As shown, the embodiment of the present invention provides a method for determining a file to be cleaned, and the method may include the following steps:
[0077] S100: Scan the storage space, and extract the first type of feature information and the second type of feature information of the target file;
[0078] Wherein, the first type of characteristic information may be a path, and the second type of characteristic information may be an ins...

Embodiments of the invention disclose a to-be-cleaned file determination method and apparatus. The storage space is scanned to extract first feature information and second feature information of a target file; whether the first feature information of the target file is the same as that of the cleanable file is judged; when the first feature information of the target file is the same as that of the cleanable file, whether the similarity between the second feature information of the target file and second feature information of the cleanable file exceeds a preset similarity threshold value is judged; and according to a judgment result, whether the target file is the to-be-cleaned file is judged. According to the to-be-cleaned file determination method and apparatus, the target file can be determined to be the to-be-cleaned file without increasing the quantity of feature information of the cleanable file in a cleanable file list, the storage space is not additionally occupied, and the system operating burden caused in a comparison process is also relatively low.
Description
technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for determining files to be cleaned up. Background technique [0002] In the mobile device, there are various applications installed. When the user uses the mobile device, these applications will create some files. For example, some pictures received by the application will be stored in the picture file. Some data needed at runtime will be stored in cache files. These image files or cache files may not be needed after use, but they will occupy a large amount of storage space on the mobile device, resulting in insufficient storage space on the mobile device. Therefore, these files need to be cleaned up to free up the storage space of the mobile device. [0003] According to the prior art, in order to realize the cleaning of mobile device files, it is necessary to pre-set a cleanable file list, which records the file feature information of several known...
