4MLinux (even in its basic version) is able to open huge amount of various archives (gzip, bzip2, xz, 7z, arc, zip, rar, ISO, ...). You can also view/open/install "alien" (i.e. not 4MLinux native) packages from Debian, Fedora, RH, Ubuntu, and Slackware (this feature is provided by a set of small scripts developed by 4MLinux). I will try to show this taking a Debian package as an example.
The procedure described below works in the exact same way for deb, rpm, and txz packages.
1) Terminal. Execute 'mc' to open Midnight Commander, and double click on the file, which you want to open:
2) PathFinder. This is the default file manger in the basic version of 4MLinux. Just double click on the file, which you want to open:
3) X File Explorer. This is the default file manger in the full version of 4MLinux. Let's double click again:
In all the above examples you can see the same script in action (it chooses the best method to open the package by checking what applications are installed in your system).
4) It is also possible to install the package using your right mouse button:
Note:4MLinux does not check any dependencies, meaning that it will install the package even if it leads to errors, so use this feature with caution.
