I have a flash disk on my handheld which is drive D. How do I access that from XTM?

When you installed XTM, you probably put the line:

DEVICE=EPOCFS.SYS C:\

into your CONFIG.SYS file. This installs the device driver to access EPOC files, and also sets up the first mapped drive, C: to point to the directory C:\ on your handheld machine.

If you also want to have some files on your flash disk, you need to use the program EREDIR which lets you map additional drives. For example, to create a DOS drive (D:) that maps onto an EPOC file system directory called D:\DOSFILES on your flash disk, you would use the command:

EREDIR D: EPOCFS\D:\DOSFILES

You probably want to put this command in your AUTOEXEC.BAT. The command EREDIR is explained in more detail on pages 12 and 13 (section 4.2) of the manual.

It is also possible to set up more than one drive redirection by loading the EPOCFS.SYS device driver multiple times in CONFIG.SYS. We recommend against doing that because it wastes memory, provides less control over drive letter selection, and slows down certain other DOS functions.
