Saving files in Zend CE

Hi, I was wondering if anyone could help me with saving files in Zend CE? When I try to save to the root directory, I get a message saying that that pathname doesn’t exist. I’ve tried several different variations, based on what the books and tutorials have suggested, and it’s not working. When I open the Zend directory, there a several sub-folders, and I thought of saving it or copying it into one of those, but I’m not sure which one. Please help! Thanks!
