"Supports plenty of file types, but interface needs work"
- Easy to use (from Windows Explorer's context menu)
- Supports many archive types, including .rar, which even old & proven products like WinZip didn't.
- It's FREE!
- The 7-Zip File Manager interface is not very efficient, and does not allow sorting by file extensions/types.
Still my favorite choice of FREE file compression/decompression utility. Just wish they can improve on the User Interface more, and soon!
