For unzipping, I've used PKZip or MSZip or PowerDesk (which includes an unzipper) but my young friend's laptop has none of these. Does XP include an unzipper? I can't find one in Windows Explorer, except references to PowerDesk (a separate enhanced verions of win explorer). Yet I never hear people reminded anymore to get a zip utility, or any reference to what's good or where to get it. The Help has one reference to zipping a folder, but not a file, and no relevant reference to unzipping.
