Commonly used compression software are

Commonly used compression software includes winRAR, 2345 Good Compression, 360 Compression, etc. WINRAR？ Is a popular compression tool, friendly interface, easy to use, and has a good performance in compression rate and speed. Its compression ratio is high, and 3.x adopts a more advanced compression algorithm, which is one of the formats with higher compression ratio and faster compression speed.

WinRAR has always had this advantage in the DOS era. After many experiments, it has been proved that the RAR format of WinRAR is generally better than that of? WinZIP？ The compression ratio of ZIP format is higher than 10% ~ 30%. WinRAR can decompress most compressed formats, and can directly create compressed files in ZIP format without the support of plug-ins.

Common terms of compression software:

1. compression format: different compression coding methods are used when compressing files, and the file structure generated by compression is also different. This compressed file structure is called compressed format.

2. Compression ratio: the ratio of the disk space occupied by the file after compression to the original file is called compression ratio. Among the commonly used compression formats, the compression of RAR format is relatively high, and the compression of ZIP format is relatively low. However, files in ZIP format operate faster.

3. Decompression: Restore the compressed file to the original file format, also known as release and expansion.

4. Compressed package: files in general compressed format are called compressed packages, such as ZIP compressed files. This file can manage the compressed files in the package under the management of the compression tool, such as viewing, deleting and adding.
