A file compressor is great for shrinking stored files, but it depresses me whenever I see a file grow instead of shrink. So what I am looking for is a file compression algorithm that never inflates any files, although it is allowed that some files (not all of course!) have the same length after "compression". Ideally it should work on files of all sizes, but I would be satisfied with a compressor that operates only on files larger than 1MB. Can you provide such an algorithm? No programming knowledge is required for this problem.

(In reply to Impossibility? by e.g.)

?  Where is there a reference of mapping an existing file onto what we want to create?

My assumption is that JLo is teasing us about what we do with "WinZip" etc. 

A lateral thinking exercise!  I'm pleased to see it's passage and the creativity that might compress an 'exe' file, don't think WinZip does that!
