Zip._matedit_1.1? Eh? a. Matedit current version is 1.6.
b. Where did you get this file from???
c. Well, 'Zip' normally means it's a Zip file. XP & ME can open zip files as folders (you should extract the contents before running a program inside one though), and the rest you should get a zip viewer program.
www.freezip.com
www.7zip.com
www.winzip.com <-- The top zip viewer. The trial version will function, and function well (it won't stop working after a month or whatever)
