Problems solved by technology

When the number of compressed files is large or the compressed file is large, the decompression speed is slow. If every time the decompression is interrupted, the decompression is restarted from the beginning, the decompression efficiency is low and time-consuming

Embodiment Construction

[0064] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0065] See figure 1 , figure 1 It is a schematic flowchart of a file decompression method provided in the embodiment of the present application. Such as figure 1 As shown, the file decompression method in the embodiment of the present application may include the following steps S101-S104.

[0066] S101. Obtain a compressed file to be decompressed, where the compressed file includes N fragment compression units, where N is a positive integer.

[0067] In the embodiment of the present application, the compressed file to be decompressed is not a compressed file of any file format, but a compressed file obtained by a specific compression method, so the obtained compressed file to be decompressed includes N fragmented compression units, for Decompressing the compressed file actually requires decompre...

Abstract

The invention relates to the technical field of data processing, and discloses a file decompression method and device. The file decompression method comprises the steps of obtaining a to-be-decompressed compressed file, wherein the to-be-decompressed compressed file comprises N fragment compression units; determining an undecompressed fragmentation compression unit in the N fragmentation compression units as a first fragmentation compression unit, and determining a decompressed fragmentation compression unit in the N fragmentation compression units as a second fragmentation compression unit; acquiring second decompressed data corresponding to the second fragment compression unit; and decompressing the first fragment compression unit, and taking the decompressed first decompressed data and the second decompressed data as the decompressed data of the compressed file to be decompressed. By adopting the method provided by the invention, the time loss caused by re-decompression from the beginning after file decompression interruption can be reduced, and the decompression efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a file decompression method and device. Background technique [0002] With the continuous development of information technology, massive amounts of electronic data appear on the Internet, including video, audio, image and text file types. Due to the limitation of network bandwidth and storage capacity, files should be compressed during transmission or storage, and compressed files should be decompressed during processing. [0003] At present, when decompressing compressed files in the industry, once there is an exception or human interruption, it is necessary to decompress again. When the number of compressed files is large or the compressed file is large, the decompression speed is slow. If every time the decompression is interrupted, the decompression is restarted from the beginning, and the decompression efficiency is low and time-consuming. Contents of the inventio...
