Tried not using / as the first character? E.G. Test.txt instead of /Test.txt

The file operations have some protection in to stop you writing all over the hdd so it could be stopping you from doing this, since on linux you'd be writing to the root of the drive

The code with try { }, though completely bad practice, would have worked and might be the only way of doing it since file() throws exceptions instead of null handles.

This problem should have some solution, even if it will be an a "idiotic" solution...For example  with timers & global vars, Lol

This Should work.
