  1. Can anyone put any file ext they want upon save and open it in the program they know works? It seems every file my brother saves has an ext that doesn’t work or open with the logical program. Will your “OpenWith” program be able to recognize it even if it has a bogus ext.?

  2. When trying to download the exe, my anti-virus gives a warning that a trojan exists.
