Is it possible to make a portable Zip utility such as “Portable 7-Zip”? I know that Windows XP can now open Zips, but what if you have a Rar, or some other file that Windows can’t open. What do you do then? Or how many of you have been working on someone else’s pc, that doesn’t have XP on it and needed to open a file only to fined they haven’t got WinZip either. I know I have. In those situations when you haven’t got the internet at your disposal to download WinZip, a program like that would be invaluable. Can anyone out there make one...?
