>any ideas why it will not unzip those files?

Nope. If WinZip is running, and the source file is where you told WinZip it is, and the target folder exists, then it should be extracting the zipped files or showing an error message as to why not. FWIW, I've used the code I posted in production and it works. I know that doesn't help you, but it's not just psuedo-code. What OS are you running? If it's NT or Win2K, could it be a matter of the VFP process not having write permissions to the target folder?
