When I launch this DOS Animator app I'm getting an error message - "Having trouble using Z drive." I mounted an A drive but it doesnt see it, it only sees the Z drive. It wants to write data to the Z drive upon start but there is no space on Z to write. How can I make some space on Z drive or create another drive it can see with space so it can write? I'm currently using the DosShell v1.9 to launch.
