What is a rar file?
RAR (.rar) is a proprietary set of a container of a compressed container, a similar zip (.zip) file. It was created by Eugen Roshal, hence the name r Oshal ar chives. Roshal also helped develop programs to use format, including popular, Winrar ™ . While the zipper format precedes this format, it has advantages over zip compression.
Software creates rars by adding one or more files to the container, giving the archive extension, .rar . Like zip archives, files can be saved in this state, but cannot be used until they are extracted or decompressed. Software like Winrar extraments files to the selection folder. Although it may sound nothing but zippered files, the format has some significant advantages.
Using the software, you can break very large files into a multi -part "bite" volume, named automatically in the sequential order. For example .R01, .R02, .R03 and so on. A newer version of WinrarUse part01.rar, Part02.rar, Part03.ra . The file distribution into small parts makes it easy to send over the network. After receiving the user, taps the first volume in the archive (eg .R01 or Part01.ra) and the installed program extracts the content and recharges all volumes into the original file with the original extension.
In addition to its ability to process large files, RAR format has other benefits over zipper format. Among them, files are compressed more efficiently, resulting in smaller file size than zip files (although compression and decompressing these files take a little longer). RAR files also include redundancy or "recovery record" stored in the archive, allowing you to repair the container that has been damaged. Newer versions of the format also support the advanced encryption standard (AES) and multi-fold.
while winrar shareware is probably the best known program, the ability to manipulateWith these files, it has been licensed for many software developers. Current versions of Windows operating systems include only native ZIP file support, which leads many users to use reserved third -party compression programs for other features they provide and the ability to process all types of files. One of the popular, free and open source compression tools is 7-zip , which also processes rar, PSIP, CAB, TAR and deb.
