Nowadays, the use of compressed files facilitates the sending or transport of large information, but in a compressed format which saves space, and thanks to the various integrated functionalities of compression solutions it will be possible to protect this type of compressed files with Various methods of encryption ..
Although it is a very popular format and available for modern operating systems, in the case of Ubuntu distributions we can notice that the system file manager does not support the extraction of RAR files nor does it allow us to create RAR files, if we try to extract the content The following error message will be displayed:
In order to enable support for the optimal extraction of RAR files, it will be necessary to install UNRAR, which is an application developed by RARLAB, and if the objective is the creation and administration of RAR files, it will be necessary to install RAR, which It is available as evidence at this time.

To extract and decompress a RAR file we have two options:
Option 1
The first consists of the graphical mode of Ubuntu, right click on the tablet and select the option "Extract here" and we will see a message indicating that the task was completed correctly:
Option 2
