Embodiment Construction

[0023] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0024] The present invention provides a method for installing and clearing external storage files. External storage is a concept relative to internal storage. External storage is generally connected to the controller through a storage interface connected to the controller. Plugging and unplugging the external storage device can realize the connection or disconnection of the external storage device and the controller. The internal memory is generally a memory storing an operating system, and for a handheld mobile device, the internal memory is generally fixedly welded on a circuit board. The external storage medium (i.e. external memory) includes but is not limited to floppy disks, hard disks, optical discs, USB and other media that ca...

Abstract

The invention relates to a method and a device for installing and deleting external storage files. The method is characterized in that data is searched by an application program through soft link symbols; the soft link symbols are stored in an external memory; the data pointed by the soft link symbols can be stored in an internal memory. The problems in the prior art that as the data stored in the external memory can not be completely deleted, disk fragmentation residue is formed, the running efficiency of the system is influenced, and the like can be solved.

Description

technical field [0001] The solution relates to the field of data storage, in particular to a method for installing and clearing external storage files. Background technique [0002] The operating system is a window for human beings to communicate with electronic products. The rich functions of the operating system are inseparable from a variety of applications. During the process of users installing applications and using these applications, applications will create a large number of files in the system, but when these applications are uninstalled, many of these files are not deleted and are still stored in the system, which can be Call it junk files. A large number of junk files and system files coexist in the storage space of the user device, the disk fragmentation is serious, and the running speed of the user device will be slowed down, making the operating efficiency of the system low. Taking the Android system as an example, with the continuous improvement of its eco...
