I recently upgraded my machine to Windows 7. It was a complete re-install and I lost the utilities I was using. Windows 7 does a nice job on .zip files, but not as nice as I was used to. And it does not handle other compression schemes at all. So I wanted to get my old utility back. I could not remember the name, and my e-mail organizing leaves a lot to be desired. So I went to the micro$oft site and downloaded their recommended product. That was a mistake. Clunky and very hard to use. Even after shelling out money to ensure I had a fully functional product, I could not stand it. I HAD to find my old utility. It took me a while, but I found Power Arc hiver again. I am a happy, happy camper. More powerful, more flexible, and easier to use. Your product rocks! Imho Thank you, Chris S.Thank you Chris for such kind words – we are here for you!
