I’m glad that it works for you but you have to know that it’s not like that for everyone. Last time I tried using MTP I had to write a script that would call rsync in a loop until all files were transfered because every time like one or two files would just mysteriously not make it across the cable.

Also, not me personally, but some people have usecases like playing video files from their phone on their tv or sending files to a printer over the cable. This wouldn’t work with MTP because most “dumb” devices like that don’t support it
