Window 7 deleted folder?

not 100% sure as id have to see it but if you go to control panel and select folder options then click on the view tab and youll notice a box you can scroll down in the view panel. in there it will have a folder that says "hidden files and folders" with the radio button selected by default to "do not show hidden files and folders", select the one below it that says "show hidden files and folders". then hit apply and ok, and check to see if your folders are there.
