RAR is a file compression format, which can compress files or folders into one or more archive files. Rar extension. The RAR format was created by Russian programmer Eugene Roshal and developed and maintained by Rarlab company.
Characteristics of 1 and RAR
Compared with other common compression formats, RAR can achieve a higher compression ratio, thus effectively reducing the file size. RAR supports dividing large files into several small compressed packages, which is convenient for storage and transmission. RAR allows users to set passwords for compressed files to ensure the security and privacy of files.
RAR has the ability of automatic error correction, and can restore the integrity of the file as much as possible even if there is an error in the transmission process. RAR can be used on various operating systems, including Windows, Mac and Linux.
The use of 2.RAR
RAR is usually used to compress and archive files, reduce file size, save storage space, and promote file transmission and sharing. Software developers usually use RAR to package software, code and resource files into an archive file for easy distribution to users or other developers.
RAR format can be used for file backup and long-term storage, which provides high compression rate and error recovery ability and helps to protect the integrity and availability of files. Because RAR has the characteristics of volume compression and password protection, it is often used to package, encrypt and decompress files in the process of network transmission and data transmission.
Comparison between 3.RAR and other compression formats
Both RAR and ZIP are common compression formats, but RAR usually has higher compression rate and better error recovery ability, while ZIP is more widely supported and applied to various operating systems and software. RAR and 7z are relatively new compression formats, both of which can achieve high compression ratio.
However, RAR is more mature in terms of stability and ease of use, while 7z is relatively slow and consumes more resources. Both RAR and GZIP are lossless compression formats, but RAR usually has a higher compression rate, while GZIP is more suitable for compressing large text files.
