I've allready searched some shareware collections, but all of them Win95 ones. Haven't looked into DOS archives, because I'm using long filenames. I still have an old Norton Utility, that does it, but only with 8.3 filenames. Oliver This can be done under MS-DOS. I don't remember the name of the utility, but there was a small program from PC Magazine (if I am not mistaken) to do this. Try searching the MS-DOS shareware archives such as shareware.com or www.cdrom.com =========================== Peter Shkabara, P.E.
