Abstract: A cache folder identification method and device, the method comprising: in the process of running target software, acquiring a plurality of sample values x1, x2, . . . xn of 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?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.

Abstract: Embodiments of the present application disclose a method and a device for file name identification and file cleaning. The method for file name identification comprises: determining a set of files to be processed; obtaining a string corresponding to the name of each file included in the set of files to be processed; for the obtained string corresponding to the name of each file, detecting whether a regular expression template matching the string is present in a preset regular expression template library; determining the detected regular expression template as a regular expression template of the file name corresponding to the string; identifying a regular expression of the file name corresponding to the string according to the determined regular expression template.

Abstract: 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.

Abstract: The present disclosure provides a processing method and apparatus for saving power, a mobile terminal, and a cloud server. The method may be applied to a client, and includes: collecting at least one of running information of an application in an operating system of the client, behavior information of the application and scenario information related to the application, to generate client characteristic information; uploading the client characteristic information to a cloud server; receiving a power saving strategy generated by the cloud server with respect to the client characteristic information, and performing a power saving operation on the application according to the power saving strategy.

Abstract: Embodiments of the present invention disclose methods and devices for folder path identification and folder cleaning. The method for folder path identification comprises: determining a set of folders to be processed (S101); obtaining a string corresponding to the path of each folder contained in the set of folders to be processed (S102); for the obtained string corresponding to the path of each folder, detecting whether there is a regular expression template matching the string in a preset regular expression template library (S103); if so, determining the detected regular expression template as a regular expression template of folder path corresponding to the string (S104); identifying a regular expression of the folder path corresponding to the string, based on the determined regular expression template (S105).

Abstract: A junk directory identification method and apparatus. The junk directory identification method comprises: obtaining a directory to be identified; wherein, the directory to be identified is a directory generated after running of an application software; obtaining the file names of the files in the directory to be identified; determining whether the file names of the files in the directory to be identified all conform to temporary file naming rule; if so, determining the directory to be identified as a junk directory. Hence, the present solution uses a method of determining whether the file names of the files in the directory to be identified all conform to the temporary file naming rule to identify whether a directory to be identified is junk file, making full use of the unique naming method when a directory automatically created by a software application caches files, and can therefore effectively identify whether a directory in an application software is a junk directory.
