[Coco] Another Coco Virtual Disk Util

Yup, it's because each of the directories on your original have a minimum of
20 sectors allocated to them instead of the default 8. The PD.SAS value is
probably $20 instead of $08 in the virtual machine that formatted that
original vhd. Do a dmode of that drive to see what the SAS value is set to.

Yes it was. The one I made today was using that one as source and copying to
a new one made with the new version today. The resulting free space is the
same whether I use the original (Archives) or the second  (Archive), so that
tells me the original is using more space than the new, but over
100,000 bytes? That's alot of wasted space.

Format defaults to 32 sector allocation. I forgot to change it to 1 sector
allocations, but EmuDisk doesn't give me an option to change it.
