"An innovative compressor with a compression ratio better than the popular WinZip, RAR and ACE."
Every so often there are new compression programs, some of them really interesting, like this WinUHA.
WinUHA is an innovative free compressor (although the author asks for an altruistic donation on their website) that is great above all because it obtains a higher compression ratio than the more popular WinZip, RAR and ACE. That makes it extremely useful to transport or send spcific types of large files.
With WinUHA you can create autorun files, and the person who recieves these files doesn't need to have the program installed in their PC.
