Re: Any zip or tgz that decompress to itself ?

I don't agree with you. The zip header format is not compressed and is not random data at all. One can take advantage of the potentially compressible header to have a zip file with the same size. It implies that the "incompressible" part size is not too high. I think that the difficulty is not to file size, but make the file respects the zip format with header and file list...

Quite a new approach: add data to an already compressed file, to make it compress better? Not impossible, but also not very probable.
