XXCOPY 2.85.8 (Freeware)

XXCOPY is simply a logical extension to XCOPY. It remains faithfully compatible with XCOPY in the invocation syntax, yet, adds many innovative features to be a very serious utility for anyone who feels comfortable in managing files in command line mode (DOS Box). XXCOPY has grown to be not just a file copy program but also file removal, search and list utility. Its short-name preserving capability makes it ideal to clone a system disk which can be made bootable. XXCOPY runs under Windows 95/98/ME/NT/2K/XP and comes with a 16-bit version XXCOPY16 which allows copying files in DOS environment using short name only (to be later expanded to long name). You may also use it for synchronizing systems. In short, it is an industrial strength utility for system administrators.
