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.
