IPC: G06F16/13
Filed: 2020-02-26
Abstract: To provide methods and apparatuses for storing a file path and accessing a local file to improve access efficiency to the local file.SOLUTION: A method monitors local files in different storage areas, the different storage areas including storage areas corresponding to different applications APPs. The method obtains file paths of the monitored local files, and stores the file paths in a preset storage area. The method obtains the file paths from the preset storage area when an instruction of acquiring local files input by a user is received, and accesses the local files corresponding to the file paths. Therefore, a terminal can directly access the local files corresponding to the file paths based on the file paths that are stored in the preset storage area, thus effectively improving access efficiency to the local files.SELECTED DRAWING: Figure 1
