I just want to suggest that one of the best ways to back up something like DXBase, is to use one of the USB jumpdrives.
I 'was' backing up to cdrw disks, numerous other hard drives on the same computer and to the 'secondary' shack computer. I just switched to jump drives, one on main computer and one on secondary. They are pretty cheap and safer than disks. And lots more portable. ----------------------------------------------------- "Thrashing is just virtual crashing. ----------------------------------------------------- Bill H. in Chicagoland
