A Xubuntu user experience journal
To be able to open/extract 7-Zip files (7z extension) in Xubuntu we need the p7zip-full package. Check bellow for instructions on how to install it.
Open a terminal window and run:
sudo apt-get install p7zip-full -y
And what about only installing p7zip, not "full" ?p7zip-full gives ZIP support but file-roller can manage those files...
The difference between p7zip and p7zip-full is that the "full" also installs 7za. 7za is a stand-alone executable while 7z uses plugins to handle archives. File Roller can not manage anything on its own, it's only a graphical interface to archiving utilities.
Thanks for explanation :)
