Try 7zip it comes on most computers now and is a good program.
Try 7Zip. You can get it from cnet.com - in their download section. They scan all programs for viruses, etc. and I have never had problems with anything from thier site (including this program - it is the one I use).
Thank you for responding so quickly. Is this the same 7Zip that is on Embird. I'll look into this.
