I was a bit confused as to what I had deleted from my vms files, and more importantly where they had come from, so I had another look at this. I downloaded Chankast Alpha v0.25 again and found a few interesting things out.
1. Chankast comes with no vms files, only the vmsbrowser.
2. By running the browser and clicking 'Write vms.bin', a vms file created. Now, upon loading the bios and accessing this vms.bin, I see that it is full of files. See the screenshot.
3. I could find no instance of a Format command (maybe I'm missing something). All there is for removing these files is the "Delete All (memory reset)" command.
So, that's where my confusion stems from.
:happy:
