I recently installed Linux in my computer since Windows gave me some problems (and I had too many games which distract me sooooo much).
Sometimes I connect my phone to my computer to save pictures and get some music on the phone so when I realized I couldn’t exchange files I got a bit worried and started to do some research 
I finally found a package that can be used with phones regardless the connection you use (Bluetoot®, USB or IR).
