     Okay; thanks for the explanation. My question is about dealing with
compressed ShrinkIt whole-disk (.sdk) files of 140k diskettes.

     Most .sdk files are automatically compressed at the time of creation
because this saves space. Something around 80k is a fairly common size. Nearly
any compressed .sdk file of a 140k disk will fit on a 140k disk image.

     Suppose you are running AppleWin (or some other emu) and have a disk image
which contains an .sdk file in 'Drive 1'. Can it be unshrinked to a target disk
image in 'Drive 2'?    

     On a real Apple II, of course, there would be no problem. ShrinkIt 3.4
would unshrink the .sdk file to the target diskette. Will this work on any
current emu? If it will and there are ways to get the .sdk files onto dsk's,
then there would be a way for emu users to access nearly everything in 5.25"
.sdk files.
