Easily Send Zip Files to PC Users For those times when you need to send a Zip-compressed file to a PC user, use DropZip. DropZip makes sending Zip files quick and easy - just drag and drop a file or folder onto the DropZip icon to compress. That's all there is to it! StuffIt is smaller. StuffIt is better. Use StuffIt compression to create the smallest compressed files - an average of 20% smaller than Zip. Plus, StuffIt archives are designed for the Mac, unlike the Windows-based Zip archive, to make sure your files are sent via the Internet safely. And, StuffIt is cross-platform and cross-language compatible; the Zip compression format is not.
