Zip files without compression


I'd like to bundle a number of big files into a single file, to make them easier to share. The files are already compressed (eg. jpeg, video etc), so I don't need compression, only archiving. How can I put them in a zip file without using zip's compression feature? I don't want to waste time trying to compress gigabytes of already compressed files.

I want to use zip and not tar file because many Windows users can't open those files.

The ZIP format has always supported archiving files with zero compression ratio, even since pkzip/pkunzip in DOS times.

Nowadays, almost all compression programs support this; 7-Zip is one of them, it lets you specify the compression ratio both from the GUI and from the command line, and it's free.
