A program has to access specific files from drive C. After testing, I found that using SUBST to emulate the folder containing the program as drive C can solve the problem. It works fine with floppy disks and RAMDDSK virtual disks, but it fails only with a CD-ROM.
D:\DOSTOOL>subst c: d:\dostool
DOS 7.1 SUBST v7.10 (Revision 4.11.1492)

Path not found - d:\DOSTOOL
Here d: is the CD-ROM drive, and the folder d:\DOSTOOL really does exist.
Is there any solution or alternative workaround? Thanks!
