I still use Defrag for oldschool DOS/Win311/95/98 virtual machine disk images. After I’ve got the VM image set up the way I want, then I’ll defrag it, then write a nulled out DUMMY.BIN to the root folder filling all the free space, then delete the DUMMY.BIN file.
Doing that greatly improves compression of the final archived disk image.

I’m guessing dummy.bin is a zerofile?
Yep
