Managing .zip files in WinXp is pretty much a thing of the past as Windows can now open them. However, WinXP doesn't know what to do with .rar files -and .rar seems to be gaining popularity. Is there any freeware that can open .rar files? I was using a piece of shareware called PowerZip. I just refuse to pay $20 for a piece of software I'll rarely use. Less important to me is to understand why .rar files seem to be more common. Zip files seem to work well and WinXP handles them natively, so why even bother with .rar? Just curious.
