 |Typing or also selecting a file not in your locale may be difficult

 |PS: Microsoft has over restriction in filename. "Com" is not allowed.

These are special names like "aux"[.any-extension??] which have
a special Microsoft (or DOS?) specific meaning, in each and every
directory (as far as i know).  lpr, nul and whatnot, i think.
Just like /dev/null, /dev/tty in Unix, but without hierarchy.
