USING FIXSIT:
FIXSIT works in conjunction with UNSIT.EXE, the freeware
IBM utility by Brian Uecchi for StuffIt files. Serious
IBM desktop publishers have long relied on Macintosh art
providers for high-quality clipart and fonts. Now, with
the improvements in Fontographer (a Macintosh typeface
design utility) and the introduction of Type-1 Tools (a
Creative Bits utility that translates MAC fonts to IBM
fonts) the challenge to keep our platforms connected
becomes even more important.
Usually, expanding files from a StuffIt archive is a
pretty easy affair. Although the IBM UNSIT.EXE utility
is a little cumbersome, and has a couple bugs, it has
proven to be fairly reliable.
But there are times when it fails to work altogether.
Instead of expanding the files, it aborts with a
terse "Unknown compression type." error message.
That's where FIXSIT comes in. Often times, in these
.SIT files, the header is incorrect. It contains
extraneous information that makes perfect sense to
Macintoshes, but not to IBMs. FIXSIT does its best to
strip this information out and leave an UNSIT.EXE-
compatible .SIT file.
RUNNING FIXSIT
To run FIXSIT, simply type FIXSIT. It will display a
list of .SIT files (if any) on the current directory and
ask you which one you want to fix. Enter the name of
the bad .SIT file and FIXSIT will take over.
NOTE: You can also type FIXSIT (filename) and FIXSIT
will run without asking for further input.
When FIXSIT completes, you will be left with two files:
the original .SIT file and FIXED.SIT, a .SIT file that
should be compatible with UNSIT.EXE.
Finally run UNSIT X FIXED.SIT, and you should be able
to retrieve all of the files from the StuffIt archive.
NOTE: The repaired .SIT file has one anamoly. In the
.SIT header, a byte is used to specify how many
files are in the archive. FIXSIT has no way of
knowing how many files are actually present, so
it sets this byte to 255. This means that
UNSIT.EXE will ALWAYS abort with an error message
when operating on FIXED.SIT. However, when
UNSIT.EXE aborts, it has ALREADY expanded ALL of
the files orginally archived by StuffIt.
FUTURE COMPATIBILITY
FIXSIT can't fix every conceivable problem that can
occur with .SIT files, nor can I guarantee it will
effectively fix .SIT files produced by future versions
of StuffIt. I can say that during my career in desktop
publishing and during the development of Type-1 Tools, I
have downloaded dozens of .SIT files from CompuServe and
GEnie. All of the files that were initially
incompatible with UNSIT.EXE worked after I used FIXSIT.
