Problems solved by technology

[0003] However, due to the inconsistency of the disk environment on the user device, it is easy to generate disk fragments, so that the application files of the application program are stored discretely on the disk, so that the reading of the application files by prefetching files is physically discontinuous , it is inevitable to perform a long-distance disk seek, resulting in an increase in disk read time, which is not conducive to improving the startup speed of the application

Abstract

The invention discloses a prefetching file processing method and device. The prefetching file processing method comprises after decompressing an application program installation package, obtaining a first prefetching file from the application program installation package, and obtaining a plurality of file logic offset blocks in the first prefetching file; sequencing the plurality of file logic offset blocks, and forming a second prefetching file with a continuous disk physical location; and preserving the second prefetching file which can be read by the installed application program during the loading process. According to the invention, the disk reading time can be reduced, and therefore the application program can be started quickly.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and device for prefetching files. Background technique [0002] Startup prefetching is a technology to speed up the startup speed of applications. The main principle is to load the application files of the application from the disk to the physical memory of the user device by reading the prefetch file when the application is loaded, so as to avoid the It takes a lot of time to read these application files from disk at startup. [0003] However, due to the inconsistency of the disk environment on the user device, it is easy to generate disk fragments, so that the application files of the application program are stored discretely on the disk, so that the reading of the application files by prefetching files is physically discontinuous , it is inevitable to perform a long-distance disk seek, resulting in an increase in disk read time, which is not conducive t...
