I downloaded a zip file from a webpage, creating a new folder for the purpose. When I go to unzip the file, I can't find the folder. I go back to the webpage to download again, and it tells me I already have the file, but I notice now there is a "folder with lock" icon next to the folder I created. This folder isn't visible at all in Windows Explorer, no matter what options I choose. (And the User I am logged in as has full administrator privileges.) How do I take ownership of this folder? I'm stumped!
