Everyone, help out. I now have an industrial control computer using the DOS 6.22 system. I used to copy files with floppy disks, but now I added a USB flash drive. However, the program doesn't have the function to copy from the USB flash drive. Is there a way to virtualize the USB flash drive as drive A? I searched online for.subst.exe, but it's not for 6.22. Is there any expert who can help solve this? Thanks a lot!
