     That's neat!-- good to hear the program was useful.

     You can convert most ShrinkIt 5.25" whole-disk archives-- .sdk files-- to
disk image form using Nulib. However, there are two 'catches':

o- Nulib won't work on .sdk files created by GS-ShrinkIt (usually, you get a
short file instead of one which is 143,360 bytes in length).  Fortunately, most
5.25" .sdk files were created using 8-bit ShrinkIt. 

o- If Nulib is successful, you get a .po (ProDOS order) disk image, which ADT
can not transfer correctly. You can convert .po to .dsk by copying the .po
image to a .dsk image on an emulator (like AppleWin) using Disk Muncher.

     The best way to do file and other non-.dsk transfers, is to use regular
telecom utilities on the Apple II and PC. You can find some A2 telecom
utilities (plus 8-bit ShrinkIt and other good utils) on .dsk image on Ground at
ftp://ground.ecn.uiowa.edu/apple2/useful.stuff/Disks/ .
