Embodiment Construction

[0035]In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] The fast index of the computer data compression processing method of the present invention calculates the relative position offset, and performs matching according to the invariable characteristics of the head of the LZ77 target string. Logical judgment and calculation; before LZ77 is implemented, build an overall quick index table, and the number of occurrences of LZ77 doing sliding window matching becomes 1 / 2 of the original k , and the complexity of its construction is only Θ...

Abstract

The invention discloses a computer data zipping and processing system comprising a file zipping and unzipping sub-module to achieve the zipping and unzipping of files in different formats and integrate functions of Zip, 7-Zip, Rar and Meta. A basic file operation sub-module is designed in the system to open, close and save files as well as adds, removes file headers and achieves multi-part archives. A file view sub-module in the system displays information of ordinary files and file directories as well as the directory of zipped files and other required information. The zipping functions provided in the invention allow a user to zip in their needs for files in different forms and can zip both files and file documents. Further, the system also provides a zipping algorithm and has better zipping rate and speed, more true to non-redundancy data files. Well developed, the system is also convenient to operate and the quality of the software in the system is brought to its maximum.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a computer data compression processing system. Background technique [0002] In this era of rapid information development, the dissemination of information or the dissemination of data can be said to be the link of information development, but the transmission of large amounts of data will inevitably have defects such as: difficult to guarantee security, large time consumption and other issues have gradually become urgent needs Problems solved, so compression software has gradually become an indispensable tool. Many shareware exists on the Internet in the form of compression and packaging. Without compression software, many software cannot be installed. Therefore, compression software is a must-have software for computers. The initial value of compression software is seen in the word "compression". Software with a high compression rate can sometimes compress...
