There's no built-in support for archives, but it can be configured to use another program for that (Xarchiver in this example, but also File Roller comes to mind and maybe others). Go to the Applications window and add a new entry with "xarchiver -e %s" in the Command field. You can also add "xarchiver -d %s" to create archives. Then you can use Open with... in the context menu to extract an archive or create one from a folder (selecting a few files instead of a folder will also work, but in a different way: using Open with... in multi-selection mode will run the command as many times as there are selected files).


It even has a portrait lock in the settings.
