The WinZip on the your computer will be fine. I have never had any problems unzipping the embroidery files with my XP software.

Like mentioned above, the zip program that XP has will work fine for unzipping embroidery designs.

How do you unzip on XP?

When you double click on the file that you want to unzip, the process should start automatically.

Thanks to all of you. I will give it a try.
Wish me luck.
