WINRAR is a popular compression tool, with friendly interface, easy to use, and good performance in terms of compression rate and speed. Its compression ratio is high. 3.x adopts more advanced compression algorithms, 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 WinRAR's RAR format is generally 10% to 30% higher than WinZIP's ZIP format. WinRAR can decompress most compression formats, and can directly create compressed files in ZIP format without the support of plug-in programs, so we don't have to worry about leaving the problem of how WinZIP handles ZIP format. This software provides you with WinRAR tutorial solutions and graphic tutorials.
