Worked great or me, with minor modifications. 1. The original expression disallowed a semicolon, but Windows allows it in file names. 2. Signs "<" and ">" should not be allowed. Here is the corrected expression, I don't know if the browser will display it correctly. If not - mofify the end of the original posted expression (starting with the "?"), to this: ?*:\"><|/]+$
Corrected expression:
^(?!^(PRN|AUX|CLOCK\$|NUL|CON|COM\d|LPT\d|\..*)(\..+)?$)[^\x00-\x1f\\?*:\"><|/]+$
