A method and apparatus for identifying a junk file of picture category, and electronic device are provided. The method included: acquiring a storage path for storing files of picture category; acquiring a filename feature of a file in the storage path; and on the basis of the filename feature, determining whether the file in the storage path is a junk file picture category.

Junk picture file identification method, apparatus, and electronic device

A cache folder identification method and device, the method comprising: in the process of running target software, acquiring a plurality of sample values x, x, . . . xof the number of files in the target folder according to a preset rule, the target folder being a folder used in the process of running the target software, n&#x2265;2; according to a preset algorithm, calculating the statistical value of the plurality of sample values, the statistical value being used to represent the degree of dispersion of the sample values; determining whether the statistical value is greater than a preset first threshold; if so, identifying the target folder as a cache folder. The method has high identification efficiency, and can continuously monitor specific software without missing a cache folder.

Cache folder identification method and device

A method and device for identifying junk picture files, which are used for a server side to identify junk picture files in cached network data. The method comprises: obtaining a directory to be detected; determining whether the number of files in the directory is greater than or equal to a first preset value; if so, determining whether file names of the files in the directory contain keywords which represent the cached network data; if the keywords are contained, determining that the files in the directory are the cached network data, and then, determining whether keywords which represent useless picture files exist in the cached network data, so as to find out whether junk picture files exist; if the junk picture files exist, identifying the found picture files as cached junk picture files; and recording a directory path where the cached junk picture files are located. By means of the above solution, the cached network junk picture files can be accurately identified.
