YemuZip

You'd think there wouldn't be any problem with using a ZIP file created on a Mac in Windows. But you might be wrong.

YemuZip will help you avoid last-minute surprises. It's a tool for Mac that lets you create ZIP files that are certain to be compatible with Windows.

You just have to grab and drop into the program the file or the group of files that you want to compress. Name the resulting file and choose the format (PC or Mac). And—voilá. That's it. Windows-compatible ZIP files.
