The only compressed file manager you need. Excellent file type support, superb compression with the .7z format. Bundled encryption and great explorer integration. It beats WinZip on every count! And it's free.

Four Compression And Archiving Solutions Compared. "If you can freely choose an archiving tool, and if you want to balance compression and processing time, 7-Zip with LZMA2 and WinRAR—both at default compression—deliver the best overall results."
