wow i was very very impress, i just got a 9 file with combine file size of 1.2 gig. down to 55mb. im not joking, and i test the files, it work fine! next time if you need to send client big file over the net, try it! http://www.7-zip.org/

it all depends on what kind of files you're compressing. With any compressor, you can only do so much, especially if files are already compressed with another algorithm. The way any compressor usually works is it finds repeated patterns within the file and makes records for where they repeat, thereby making the size smaller by replacing the actual data with indexes. So if a file has been put through such treatment already, or by nature doesnt have much repeating data, it wont compress very well no matter what you use, while some files compress down to a fraction because of the opposite.

well, that's with tagged compression... there are other algorithms that work differently (such as wavelets for video/audio). i'm no compression expert, but AFAIK tagged compression (as seen in ZIP, RAR, RLE, etc) is pretty much tapped out, but someone may come up with a new, innovative method that works better.

"1.2 gig. down to 55mb"
I'm really interested in knowing what files you compressed, 1.2GB hints it's rich media but 55 is a bit extreme for lossless compression
