OK, why I didn't look for something like this before, I don't know...!!! I found a free program called "The Extractor 1.4.2" that takes the pain out of unzipping all those downloaded files... and I have a TON of stuff I'm still downloading and unzipping from this weekend.
I am using Windows Vista, and this program is working GREAT. A friend of mine uses Windows XP and it's working really well for her too.
NOTE THIS LINK TAKES YOU TO ANOTHER SITE where you can download the program.
This is a free download, I'm not getting anything from this, just sharing it because it's been SO HELPFUL!!!
