OPL and disks

Memory disks in the D: drive may be used in the same way as the internal memory by specifying D: where you would usually specify C:.

There are two main reasons for using disks:

• To provide more room for storing data.
• To make backup copies of important information, in case you accidentally change or delete it (or even lose your machine).

The internal memory, memory disks use a FAT directory structure, the same as that used by disks on PCs. For more details, see Advanced Topics.

The ROM drive, Z:, can also be read from. However, Z: is read-only.
