files of old 5.25" wares. (Balloon does not currently support whole-disk
archives.)
Naturally, things are somewhat more crowded on 64K Apple II's. On these
machines, the functions are separated. SHRINK creates .SHK files and UNSHRINK
unshrinks them.
On a PC, the utility NuLib (v3.24) lets you view contents and unshrink most
kinds of .SHK files. (There is a handy option to unshrink and convert Apple II
text files to PC text format.) It will not unshrink IIgs files with resource
forks.
Here is a simple one-line batch (text) file program for easily viewing the
contents of .shk files you download to a PC (just double-click on the file
name):
c:\nulib\nulib v %1 |more
The above is for NuLib.exe located in folder c:\nulib . Save the text as
nulibv.bat in c:\nulib and tell Windows to use c:\nulib\nulibv.bat as the
'application to perform action' for doing an Open. (You do this by selecting
View--Options in the My Computer window and editing the file type info for .shk
files.)
NuLib can also convert 5.25" .SDK files into .PO (ProDOS order) disk images
which can be used by Apple II emulators. This works for .SDK files produced by
8-bit ShrinkIt but not for those produced by GS-ShrinkIt.
The unshrinking process is very speedy and the size of a compressed
ShrinkIt file is, often, around half that of the original files it contains.
This makes .SHK files very handy for archiving your software. And, since a
ShrinkIt file also preserves filetype information of contained files, ShrinkIt
has become the preferred format for uploading and storing Apple II files on the
internet.

003- How do I get ShrinkIt or GS-ShrinkIt going on my
Apple II?
Getting GS-ShrinkIt v1.1
If you do not already have Balloon or an earlier version of GS-ShrinkIt,
there are several ways to get GS-ShrinkIt going once a file is downloaded and
transferred to your IIgs. Here are the two easiest ways:
A. The Self-Extracting (.sea) version
A IIgs .sea file is a IIgs application which self-extracts the file
contents when executed from the usual Finder desktop display. Since the file
gshk.sea will, most likely, arrive as a Text type file, you will need to change
the file's filetype to $B3 (S16) before it can be executed.
