Hi,

As I could not understand why the Emulator Hard Disk Image was so
Large (27 Megs - HUH), I wasted the download time to take a look at it.

Most of the size of the image appears to consist of web pages, not CoCo
related as far as I could tell with a quick scan.

I wonder if there is any personal data in the file. To me it appears to
be a dangerous thing to make available to one and all.

If you delete all the unnecessary files and then zero the unused space
using the following program you will find that the file ZIPs up to a
much smaller size.

If you write a simple program to write to any file $00 bytes, a program that
never stops until it fills the emulator disk.

Then when you delete the file, you will find that ZIP and other archivers
will compress the file tremendously!
