Mobile terminal data extraction method and device, equipment and storage medium

The invention discloses a method and a device for extracting mobile terminal data and a storage medium. The method comprises the following steps: acquiring a directory hierarchy of a subdirectory in a target directory; when the number of the directory levels is greater than a preset number of levels, executing a data extraction command after traversing the cache to a preset progress; and when the number and the proportion of the fragmented files of the files in a certain subdirectory are greater than a preset threshold value, packaging all the files in the subdirectory before executing a data extraction command. According to the multi-aspect reasons caused by low efficiency of data extraction in the prior art, a targeted technical means is adopted, and the method comprises the following steps: superposing traversal time and data extraction time so as to make full use of the time of a traversal process; before data extraction, a huge number of files which are seriously fragmented are packaged to reduce handsha
