It compresses the file just like an .rar or .zip. Only it does it transparently.
So there will be a delay when you open/read as it decompresses/compresses.
Obviously this won't help if the file already uses compression , .mp3, .jpg, .avi ect...
It also turns the text blue.
I just compressed a DVD Rip, uncompressed 4.11 GB, compressed 4.11 GB, video is mpeg2, audio AC3.
