Fedora by default don't support .rar format. Whether it may be GNOME, XFCE or KDE it won't support .rar format. Archive app that I have in my Fedora GNOME desktop is Xachiever. You need to install a plugin kind of software called unrar, to open .rar file.
App name - Unrar
App size - 115 KB
Installing time - less than a minute
Issue: How to open RAR file
Solution:
This software can be installed by two easy steps. Just enter the two commands in Terminal.
1. Adding RPMfusion repository:
yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
2. Installing UNRAR software:
yum -y install unrar
After following above steps you will be able to open RAR files. Sometimes you may have added RPMfusion repository before for installing some other software. In that case, after giving the first command you will get error like 'nothing to do'. If it is the case, directly enter the second command.
Now you can open any RAR file with whatever achieve software you have. Unrar is not a stand-alone software and you don't get any icon/shortcut to launch that app.
