Sebastian Any file in general and would be different commands.
Example
Tahoma2d.AppImage runs from terminal but not menu or Nemo Unless
I use this (Exec = path/to/tahoma/Tahoma2d.AppImage -TAHOMA2DROOT path/to/tahoma/tahomastuff) for a menu item.
So If running from Nemo would have to add (-TAHOMA2DROOT path/to/tahoma/tahomastuff) to the end of the
Tahoma2d.AppImage and see if it works from Nemo.
My gut feeling is its not finding its Files so wanted test run it that way from Nemo.
I though that would be something handy for future things if it wasnt to invovled in doing so.
Sorry about being so unclear.
