1. Introduction
What is AutoSqueeze
AutoSqueeze is a software utility for the Apple Macintosh that will allow you to store more information on your computer. AutoSqueeze allows you to mark any file or folder as "automatically compressed". The "automatically compressed" version of a file looks just like the original file except that it requires much less space to store on your Macintosh. Expanding a compressed file returns it to its original form so you may use it like any other file. AutoSqueeze will automatically expand "automatically compressed" files when you use them and automatically compress them again when you are not using them.
Any file may be marked as "automatically compressed" and these files may be used by applications just like any other files. You never have to run the AutoSqueeze program because it will automatically compress and expand files in the background when appropriate.
For example, suppose you have a file named "my file compressed". When you are not using it, " my file compressed" is compressed and so it requires much less storage space. The moment you use "my file compressed", such as when you double click on its icon in the Finder, AutoSqueeze automatically expands it in the background, so it looks like any other file. The moment you are done with the file, AutoSqueeze will automatically compress it again in the background.
You may also use AutoSqueeze to mark an entire folder as "automatically compressed". Any file or folder that is stored within an "automatically compressed" folder is also "automatically compressed".
AutoSqueeze can also create archive files. Archive files are compressed but are not automatically expanded or compressed. Archive files are useful for sending information over a network or a modem, or storing in a backup.
System Requirements
AutoSqueeze requires at least a Macintosh Plus with 1 Megabyte of RAM. You should use version 6.0 or later of Apple’s system software.
2. Installing AutoSqueeze
Before installing AutoSqueeze, you should first make a backup copy of the AutoSqueeze file. AutoSqueeze is not copy-protected, so you may make as many backup copies as you like. To install AutoSqueeze, copy the AutoSqueeze file to the System Folder of your startup volume. Restart your Macintosh with AutoSqueeze in the system folder.
After it has been installed, AutoSqueeze will automatically run each time you turn on your Macintosh. When you start your Macintosh, the AutoSqueeze icon will appear at the bottom of your screen. If you do not want AutoSqueeze to run, hold down the mouse button while your Macintosh is starting. AutoSqueeze will not install, and will instead display its icon with an “x” over it. Note, that if AutoSqueeze does not install, then you will not be able to use automatically compressed files.
IMPORTANT: To run AutoSqueeze, you must make sure that your startup disk is not write protected and that it has enough free space for AutoSqueeze to process files. AutoSqueeze needs working space on your disk to hold temporary data only while it is currently processing a file. Your disk should have enough free space to hold an expanded copy of your largest "automatically compressed" file.
3. Using AutoSqueeze
Marking files and folders as "automatically compressed"
You mark any file or folder as "automatically compressed" by including the word "compressed" at the end of the file's name. Some examples of names for compressed files and folders are:
sample compressed
sample is compressed
sample COMPRESSED
SAMPLE COMPRESSED
Some examples of names that do NOT indicate compressed files or folders are:
sample
compressed sample
sample compressed file
sample compress
sample cmpres
When you mark a file or folder as "automatically compressed", it will be immediately compressed. From then on, when you use that file it will be expanded and when you finish using that file it will be compressed again.
As a precaution, AutoSqueeze will not treat any file that is directly or indirectly contained in the System Folder as "automatically compressed". AutoSqueeze does this because files in the System Folder are used when your Macintosh is started, and so they may be needed before AutoSqueeze installs.
Compressed Folders
You may also use AutoSqueeze to mark an entire folder as "automatically compressed". Any file or folder that is stored within an "automatically compressed" folder is also "automatically compressed". If you move a file into an "automatically compressed" folder, it becomes "automatically compressed" even if the file name does not end with "compressed". Any file is "automatically compressed" if either its name ends with "compressed" or it is stored in an "automatically compressed" folder.
For example, suppose you create a folder named "folder compressed" and initially it contains no files. Now, move a file named "my file" into "folder compressed". AutoSqueeze will automatically compress "my file" as it is moved into "folder compressed". "my file" will now behave as an automatically compressed file, even though its name does not end with "compressed". If you double click on the icon for "my file" it will be expanded by AutoSqueeze automatically as it is opened by its creator application. If you later move "my file" out of "folder compressed", into a folder that is not "automatically compressed" then "my file" will no longer behave as an automatically compressed file. AutoSqueeze will automatically expand "my file" as it is moved out of "folder compressed".
Creating and Reading Archive files
AutoSqueeze creates and expands archive files with the AutoSqueeze Control Panel Device. Archive files are compressed but are not automatically expanded or compressed. Archive files are useful for sending information over a network or a modem, or storing in a backup.
To use AutoSqueeze Control Panel Device, you must first open the Control Panel Desk Accessory. Select the AutoSqueeze icon to open the AutoSqueeze Control Panel Device.
The Retrieve... control will prompt you to select an archive file to read and where to put the expanded file. Reading the archive file will create a normal expanded file, but will not change the archive file.
The Archive... control will prompt you to select a file to be archived, and where to put the archive file. Creating an archive will not effect the original file.
4. Troubleshooting
Below are some potential problems and likely solutions for AutoSqueeze users.
Q. AutoSqueeze is not installed, and now I cannot use an "automatically compressed" file
A. You should not try to use "automatically compressed" files when AutoSqueeze is not installed. You also should not mark an "automatically compressed" file as a normal file when AutoSqueeze is not installed. If a file ever becomes unreadable because of these or any other reasons, restart your Macintosh with AutoSqueeze installed, mark the file as "automatically compressed" and then mark it as a normal file by removing the "compressed" suffix from its name.
Q. AutoSqueeze will not install when I start my Macintosh
A. To run AutoSqueeze, you must make sure that your startup disk is not write protected and that it has enough free space for AutoSqueeze to process files. AutoSqueeze needs working space on your disk to hold temporary data only while it is currently processing a file. Your disk should have enough free space to hold an expanded copy of your largest "automatically compressed" file.
Q. AutoSqueeze will not expand some "automatically compressed" files
A. To run AutoSqueeze, you must make sure that your startup disk is not write protected and that it has enough free space for AutoSqueeze to process files. AutoSqueeze needs working space on your disk to hold temporary data only while it is currently processing a file. Your disk should have enough free space to hold an expanded copy of your largest "automatically compressed" file.
Make sure that AutoSqueeze is installed, and there is plenty of free space on your startup disk. If you have an application that does not work with "automatically compressed" files, even when AutoSqueeze is installed, then make sure all files used by this application are not "automatically compressed". This may mean moving the files out of an "automatically compressed" folder before using them.
Q. AutoSqueeze will not compress files in the system folder
A. This is intentional. AutoSqueeze does compress any file in the system folder because these files may have to be used when AutoSqueeze is not running.
Q. Some application will not work with "automatically compressed" files
A. AutoSqueeze has been extensively tested for compatibility with most Macintosh applications. If you have an application that does not work with "automatically compressed" files, even when AutoSqueeze is installed, then make sure all files used by this application are not "automatically compressed". This may mean moving the files out of an "automatically compressed" folder before using them.
