What is a .RAR File Extension?
For users who don’t know, a RAR file is a compressed file that is split into a set of multi-volume files. This is usually done in cases where there are large file sets that are needed to be shared or transferred, hence are compressed into a zip file. Similarly, for zip files, when they are transferred or downloaded from the internet need to be extracted. A number of tools are available to help extract and compress these files within seconds, regardless of their size or quantity.
Extracting RAR Files in Linux distributions
RAR is a free tool that is pre-installed on Windows operating systems but unfortunately doesn’t support Linux platforms. If you will try extracting in Ubuntu, the archive manager will show you the following dialogue box:
