All files at the same "level" are identical. The 4GB file contains zeros only. I think these "data" could be compressed into even smaller size using some different methods.

It would be interesting to see how small it could be made. I posted a link earlier, but here it is again with a quote: http://www.maximumcompression.com/compression_fun.php http://www.maximumcompression.com/compression_fun.php > 'What is the best compressor to get really extreme compression?' is a question often asked on the internet. The achieved compression ratio of course depends on the quality of the compressor used, but the type of data that is being compressed is much more important. To show this I created a tiny 115 byte rar file. When you decompress it, it will turn into a textfile of almost 5 MB (a compression ratio of 99.998%). Here it is: test.rar. Note: Turtle 0.07 compresses the same file to 49 bytes, Hook09c (with switches 3 1 1 1) to 36 bytes and UHBC (with switches -b128m -m3) to 24 bytes!!. I enjoy watching this "code golf" style competing to optimise one feature of something.
