Free compression tools software for mac

Archive a lot of files? Do you wish you had access to more file compression methods than Apple offers from the Finder but without the price of StuffIt? Enter Compress. Compress is a simple way to decrease file sizes. Not only that, but its free!
Compress gives you support for .tar, .gz, .bz2, and even .zip compression. Now you can send files in any of the geeky compression methods that you want. Not only that, but Compress also decompresses for you.
It can handle files that have been compressed many times. Want to tar then gzip a folder? Compress will let you do that. Got a file called "folder.gz.tar"? Compress will extract those files without breaking a stride.
Using Compress couldnt be easier. Simply launch the application and drag a file or a folder onto the main window. Compress handles the rest from there. If you drag a compressed file onto the window, Compress will decompress it. It can do multi-step compression and decompression without any extra hassles.
Enhancements:
- Now a universal binary
- Adds dmg compression
- Improved tar compression
- Improved gzip compression
- Improved bz2 compression
- Contains latest to date p7zip (7za) command line application.

Here is a little AppleScript application I threw together for compressing your movies into codecs suitable for VJ applications. Its a batch compression utility for those who dont have cleaner or Squeeze, heck you dont need QuickTime Pro. It lets you choose from 20 different compression settings that you might find usefull then saves them to a folder of your choosing. Presets for SheerVideo [ http://www.bitjazz.com ] will only work if you have installed the codec.

This is an AppleScript, so you are all welcome to edit and improve it. You can also make your own preset files and add them to the script and post them to this thread. In the future I will make it into an AppleScript Studio application with a completely Aqua interface with drag and drop.

Please post any comments or suggestion on our forums at http://forums.vidvox.net
