UNSTUFF is a program that can decompress the contents of StuffIt archives
including archives created with StuffIt 1.5.1 through StuffIt Deluxe 3.0.3.
Items which have been encrypted or optimized (with a StuffIt compression
optimizer) cannot be unstuffed by this version of UNSTUFF.

You may freely distribute this package to anyone who needs access to StuffIt
archives provided that UNSITINS.EXE (the installer that includes UNSTUFF.EXE
and this file, UNSTUFF.DOC) is distributed in whole. Although you can
distribute this product to your friends for free, it cannot be redistributed
as part of a commercial product without a license from Aladdin Systems, Inc.
Aladdin Systems allows free distribution of the UNSTUFF package on all major
online services, bulletin boards, and user group disks.

What is StuffIt?
StuffIt is the Macintosh industry standard compression and archiving
application. Most Macintosh telecommunication users and users who wanted to
save disk space were never caught without their most recent version of
StuffIt. Aladdin Systems provides the StuffIt program in shareware (StuffIt
Lite) and commercial versions(StuffIt Deluxe). Each has its benefits.

For years, StuffIt Deluxe has been able to access PC compressed archives, but
PC users were not able to access StuffIt archives. Now with this UNSTUFF
program, PC users also can UnStuff files from StuffIt archives. As a PC
user, you'll see thousands of StuffIt archives in the Macintosh (and some
other) forums on online services and BBSs. With UNSTUFF, you'll have access
to these files! As a matter of fact, online services such as CompuServe and
America Online have made StuffIt archives their recommended standard method
of posting Macintosh files.

What is a StuffIt archive?
A StuffIt archive is a file that contains one or more compressed files and
directories. Most StuffIt archives have the ".sit" extension in their
filename so they are easy to recognize.

There are three advantages to storing documents in an archive: (1) archives
usually contain compressed files, and thereby save space on disk and reduce
the time it takes to transmit them over phone lines or networks; (2) files
stored in an archive can be sent over networks and telecommunication lines
as a single file making it easier for other people to retrieve all related
material; (3) associated files can be kept in one archive for easy retrieval
and backup.

Terms and Conventions
An "archive item" is any file or directory located in a StuffIt archive.

"Archive.sit" is used to indicate any StuffIt archive. You should type the
name of the archive that you wish to indicate whenever you see "archive.sit"
used in this documentation.


Embedded Archive Support (MacBinary and AOL headers)
StuffIt archives that are embedded inside of other files can now be recognized.
This means that even if StuffIt archives have a MacBinary header on them, they
will be UnStuffed. StuffIt archives that have any kind of custom header placed
on them, such as by America Online, are also able to be UnStuffed.

StuffIt 1.5.1 Archives
We've fixed every known problem with handling StuffIt 1.5.1 archives except the
one shown below in Known Problems.

DOS File Name Extensions
Macintosh file names can have up to 32 characters in their file name and can
include spaces. Since DOS file names can only support 8 characters plus an 3
character extension after a period, some file names need to be truncated while
they are being UnStuffed.
Plain TEXT files will now be named with a ".TXT" DOS file convention extension,
if they don't already have an extension.
(If you have any suggestions for naming conventions for other types of files,
please let us know!)

Known Problems
The following problem was known to exist at shipping time; however, we
chose to ship this version because it offers significant improvements over
the previous version.
* In some cases, UnStuff/PC doesn't see all the files in a StuffIt 1.5.1
archive, and so the program won't display or UnStuff those files it
doesn't see.


UnStuff Archive Contents
YOU TYPE: unstuff archive
YOU TYPE: unstuff archive.sit

This command extracts every item from the archive indicated into the current
directory. The above example indicates an archive named "archive.sit". It is
not necessary to type the ".sit" extension. You may include optional
parameters in the command line either before or after the archive name to
modify how the unstuffing process will work. For example, to have UNSTUFF
walk you through an unstuffing process, you can type the following line:
unstuff -i archive
where "archive" is the actual archive name.
See "Interactive Mode" below for detailed explanation of the "-i" option.

Display Help
{none} = display help
-h OR -? = display help

YOU TYPE: unstuff
YOU TYPE: unstuff -?
YOU TYPE: unstuff -h

UNSTUFF (tm) version 1.1, Freeware decompression utility by Jody P. Nickel
Copyright (c) 1992 Aladdin Systems, Inc. and Raymond Lau. All Rights Reserved.
Extract files from StuffIt (tm) 1.5.1, and StuffIt Deluxe (tm) 1.0-3.0 archives

Usage: UNSTUFF [options] [archivename[.sit]]
{none} = display help
-c[rlf] = do CR -> CR LF translation on Mac text files
-d = don't create directories
-h OR -? = display help
-i = interactive. Prompt to UnStuff each archived item
-l = list archive contents
-lv = verbose (more detailed) listing
-mb = UnStuff each file into MacBinary format
-n = UnStuff files from archive that are newer than existing files
Any files in the archive that are not on disk will also be
-o = output, UnStuff to this directory
-r = replace existing files/directories without asking
-t = test the integrity of the archive

Commercial distribution restricted. For information, contact Aladdin Systems,

Convert Text File Line Endings from Macintosh to DOS
-c[rlf] = do CR -> CR LF translation on Mac text files

YOU TYPE: unstuff -c archive.sit
YOU TYPE: unstuff -crlf archive.sit

In a Macintosh text file, each line or paragraph ends with a carriage return
("CR") character. On a DOS compatible machine, text files typically have
each line or paragraph terminated by a carriage return together with a line
feed character ("CR LF"). If you use this option, UNSTUFF will automatically
convert all carriage returns to carriage returns/line feeds ONLY when
unstuffing text files from an archive.

Don't Create Directories
-d = don't create directories

YOU TYPE: unstuff -d archive.sit

StuffIt archives may contain directories. If you don't want subdirectories
created, and you want all the files in the archive to be unstuffed into a
single directory, use the -d option.

Interactive Mode
-i = interactive. Prompt to UnStuff each archived item

YOU TYPE: unstuff -i archive.sit

UnStuff "filename" to C:\DOCS\filename ?

Interactive mode leads you through the unstuffing procedure by asking if you
want to unstuff each file. UNSTUFF will accept your first keypress as the
answer to the question. Press "Y" to unstuff the file keeping the same name
as in the archive. Press "N" to skip this file and go on to the next file in
the archive. Press "R" if you want to unstuff the file, but want to give it
a different name. Press "C" to cancel the whole interactive unstuff process,
and get back to the DOS prompt. Interactive mode is useful for unstuffing an
individual file without having to unstuff the whole archive.

List Archive Contents
-l = list archive contents

YOU TYPE: unstuff -l archive.sit

Name Saved
--------------------------------------------- -----
ReadMe.txt 82%
Docs.txt 78%
File3 82%
MyDir 59%
test1 55%
test2 60%
6 Items 73%

The -l option is used to display the names of the files and directories that
are stored in the archive file. The first column displays the name of the
file or directory ("item"). Items that are found within a directory are also
listed but they are indented after the directory name. The second column
shows how much space was saved due to compression. The space savings are
indicated by a percentage. For example, if the percentage shown is 73%, it
means that the file was compressed down to 27% of its original size. The
larger the percentage the more the file was compressed.

Verbose Listing
-lv = verbose (more detailed) listing

YOU TYPE: unstuff -lv archive.sit

Name Type Crea Label Date Expanded Stuffed Saved
----------------------- ---- ---- ----- -------- -------- ------- -----
ReadMe.txt TEXT MSWD - 1/28/92 53275 9325 82%
Docs.txt TEXT MSWD - 10/ 9/91 17050 3601 78%
File3 TEXT MSWD - 9/20/91 10031 1737 82%
MyDirectory 2 Items 11/22/92 45792 18362 59%
test1 TEXT MSWD - 5/19/92 6144 2729 55%
test2 TEXT MSWD - 11/11/92 39424 15633 60%
6 Items 126372 33025 73%

The verbose or detailed archive listing shows more specifics than the simple
listing accessed with the -l option.
The Type column shows the "type" attribute that the Macintosh assigns to
this type of file. A typical type is "TEXT".
The Crea column stands for "Creator" which is the attribute that indicates
which application created the file. A typical creator is "MSWD", which
indicates that Microsoft Word created the file.
The Label column displays the Label assigned to the file by the Macintosh
Finder. UNSTUFF will display the default labels, and not labels customized
by users.
The Date column displays the date the archived item was modified.
The Expanded column shows the original size of the item in bytes.
The Stuffed column indicates the size that the item occupies in the archive,
that is, compressed size.
The Saved column displays how much space was saved due to compression. This
is the same column that is displayed in the simple listing ("-l").

UnStuff into MacBinary format
-mb = UnStuff each file into MacBinary format

YOU TYPE: unstuff -mb archive.sit

Each file will be unstuffed and placed into a MacBinary format. Since a
Macintosh file is composed of two pieces (a data fork and a resource fork)
and a DOS machine only recognizes one piece (the data fork), a Macintosh
file cannot reside on a DOS machine and keep its resource fork unless its
stored in MacBinary format. Most telecommunication programs can un-MacBinary
a file and there are also shareware programs that can un-MacBinary a file.

UnStuff Newer Files
-n = UnStuff files from archive that are newer than existing files
Any files in the archive that are not on disk will also be

YOU TYPE: unstuff -n archive.sit

Before UnStuffing, each file in the archive is compared to the same-named
file on disk. If a corresponding file is not found on disk, the file will be
unstuffed from the archive. If a corresponding filename is found on disk AND
the file to be unstuffed has been modified more recently than the file on
disk, the file in the archive will be unstuffed.

Output to Specified Directory
-o = output, UnStuff to this directory

YOU TYPE: unstuff -o B: archive.sit
YOU TYPE: unstuff archive.sit -o B:

This option will unstuff files to the specified directory. Notice that
UNSTUFF will accept command line options before or after the archive name.
The most common place to use the -o option is after the archive name.

Replace Existing Items without Asking
-r = replace existing files/directories without asking

YOU TYPE: unstuff -r archive.sit

If UNSTUFF encounters an item with the same name in the destination
directory as in the archive, it will not unstuff the archived item. To make
UNSTUFF automatically overwrite items with the same name, include the -r
option in the command line.

Test Archive Integrity
-t = test the integrity of the archive

YOU TYPE: unstuff -t archive.sit

UNSTUFF will check the integrity of the archive by verifying that the files
in an archive are stored correctly and will be unstuffed flawlessly.
