How different is it from normal archieving? I created a squash file and mounted it and then deleted squash file. the mounted folder. stll seems to work. So it creates another copy?? then wat is the use? It would be good if it read from the file itself rather than creating new.

A filesystem with excellent performance and reliability, I use it in combination with unionfs & reiser on my laptop.

Unlike "normal archiving" this is used for filesystems - such as running an actual system. Things like routers, bootable cds, and similar. The anonymous thumb down from the end of 2009 is a thumb down from a user who did not understand the concept whatsoever, and tried to use it like a "hammer" when the actual use of the tool is "pumping water out of a well." No, it doesn't do well as a hammer. It's NOT a hammer. Please, remove both this review and the review prior. This review is to simply offset the negative situation caused by someone who didn't understand trying to use this product incorrectly.

Combined with a union fs SquashFS is all you need. It is great!
