I use Powerdesk Utilities for file management (I hate the Windows explorer junk. They still don't seem to know how to do the job well.) Powerdesk has a builtin zip tool, and Quickview which allows me to view most files right in the file manager. It's so easy to pretty much have one program to handle all that stuff. Sit is something associated with a Macintosh. In my estimation, Macs are a good idea. But Apple just never really managed to get the Mac to the point where they equalled the PC in the marketplace. I used to work for a computer store, and I saw first hand how badly Apple handled their products. Another long story for another day perhaps. I walk into a computer superstore, and look for Macintosh stuff. You'll find it in a corner of the store somewhere. The PC stuff occupies the rest of the store. I'll stick with PC's. I'll stick with zip.
