CHRISTEFANO  Thanks! I've been looking a graphical zip archive utility that can encrypt files, works with Snow Leopard and is free. (See http://news.ycombinator.com/item?id=939443 for the whole story.)  
(Version 3.0a6)

LIKOS  This app looks great. I love the archive individually option!

Please add the option to set preferences for Disk Image Archive option. (Compression type, etc.)  
(Version 2.4a4)

TRIP2ME  I modified it and embeded info-zip and 7zip into it.

I added multi-volumes archives, compress ratio and password options.

Zip archive mode supports an option to customize filename encoding such as Windows codepages. 7zip supports an options to convert Unicode normalization in NFC which is well used in Windows and Linux. Above two options will help the users who use non-ascii filenames when exchanging archive between Mac and Windows & Linux.

You can use this freely. If you have any questions or problems, ask me anything, please.

If you interested in this apps, visit the below link. Sorry for Korean language only page advanced.

MR.LON  SIMPLY THE BEST!!!

ST00P!D M0NK3Y  Oh yeah...also...a progress bar would be nice.

ST00P!D M0NK3Y  This is exactly what I've been looking for!

One suggestion though. When adding individual files that aren't inside a folder, it will keep the extension in the file name after archiving. For instance, after archiving this app to a .zip archive, the new name is CleanArchiver2.4a2.dmg.zip. If you could allow this app to remove the .dmg file extension (or any other extension for that matter - - like YemuZip does), that would be great.

FRANSIK  A must have.

If I had a wish open, I would join Fossman's request from March 6th 2005 concerning the 7-zip/ 7z format. Or at least RAR with password protection?

Many thanks to the dev.

VIRAMOR  Great little program, solved all my problems. Previously I was attempting to use the multiple .ds_store removing programs, but soon discovered taht wasnt my only problem. I've been using the simple create archive feature in finder for my folders before emailing them off to a PC machine, but doing that created extra files. This program creates zip files flawlessly without the extra trash.

JEFF EDSELL  Fantastic! I've been waiting for something exactly like this.   
(Version 2.3)

KORRUPTOR  Absolutely spot on. Does what it says on the tin. Good job fella...  
(Version 2.3)

FOSSMAN  Very nice. Please consider adding LZMA (7z) support.

FRITZ  I wasn't able to mount the disk image (the .dmg file) but I compiled the source with Xcode and the program runs nicely and is easy to use with drag and drop.

Great tool !
