How To Backing Up Visual FoxPro Setup Disks

SUMMARY

This article explains how to make a backup copy of a set of installation disks prior to installing Visual FoxPro. With the exception of Disk 1, Visual FoxPro disks use a format called DMF (Distribution Media Format). DMF increases the capacity of a 3.5-inch disk to approximately 1.7MB, thus reducing the number of disks needed to install Visual FoxPro. Because of this new format, DMF-formatted disks cannot be copied using the MS-DOS DISKCOPY command, or any other conventional method of copying floppy disks. However, the contents of the disks can be transferred to another storage device, such as a local hard disk, and then backed-up using tape backup or similar software.
