[Coco] Another Coco Virtual Disk Util

[Wayne Campbell]

I have more info on EmuDisk. The drag-root to copy disk didn't work. Below
is my description:

What I did (all in EmuDisk):
Create a new vhd image.
Format the image.
Drag each file in the root dir of the source image to the new image.
Drag each directory in the root dir of the source image to the new image.
I did not copy sub-dirs above the root level separately.
I let EmuDisk handle the sub-directories.
Source image free capacity (in BYTEs): 89196800
New image free capacity (in BYTEs) after all copying is done: 89308928

  89308928
 -89196800
  ========
    112128 BYTEs free that aren't free on the source image.

When I tried dragging the root directory to a freshly re-formatted image, I
got the Importing dialog, but nothing ever appeared as being copied. After
about a minute I closed the Importing window and the destination image and
then re-opened the image. It was as though I never tried to drag anything.
I do not know what that is about, and I can't say the two things are
related, because the source image may have allocated sectors in the FAT
that aren't really being used anymore. I've seen it on every hard disk I've
ever looked at the file structure on. They all get that way and after a
time you have to re-format just to reclaim the lost space.

What I could use is for EmuDisk to tell me how many files are in each
directory (not including '.' or '..'). It does not have to account for
files in sub-directories in that directory, but a count of files and
sub-directories in that directory, and total of both would be sufficient
for each directory or sub-directory on their own.
