You don't need a program to make a zip-file. Just select the files in Windows Explorer, right click, choose 'copy to' and select 'compressed folder/zip file'. That's all.
I had a small program that allowed my do zip avi files and then someone else could unzip them. Some where alone the line my computer had a hiccup and it was gone. I don't remember where I got it from. It was a free.bee. Can any one help me with this?
