I wrote my filec program a very long time ago -- the first version was way back in 1987. At that time it worked in DOS; as time went on, I made slight modifications so that it would also work at a DOS command prompt inside Windows.
My filec program does not work in the newer Windows operating systems -- Windows 2000, Windows XP, Windows Vista, and Windows 7. But the good news is, similar functionality is built into Windows itself now:
EnableExtensions, equal to 1
CompletionChar, equal to 9
After you make those changes and re-run
Tab key will do filename completion. If there is more than one matching filename, press
Tab more than once; it will cycle through all matching filenames.
