Re:Where have we heard this one before? (Score 1)

Once upon a time, my VP bought into a firm that had discovered a guaranteed-perfect compression algorithm: it would reduce the size of any data file, no exceptions.

Yeah, it's called rm, isn't it? You can even use the flags '-r' for recursive (compress the compression for even more savings) and '-f' for flatten (makes the result occupy even less space than before). Run rm -rf from the root directory and just watch how much disk space frees up. Amazing!
