The LExE application was designe to be a small freeware utility that lists all executable extensions on *your* system. The Windows registry entries that determine which files are executable can vary from system to system, and this program will find those extensions that are marked as executable on your particular Windows installation. You will also be able to see if there are any suspicious entries marked as executable - on most systems the list should just read .exe, .scr, .com, .bat and .pif.
