Hi Kenneth, Can you please try holding Ctrl+Shift+N all at the same time to create a new folder? This is the keyboard shortcut. Has this been happening for a long time or only recently? Have you turned your computer off and then back on again since you have started seeing this problem?

Hi Kenneth, If this is a recent problem, try using the System Restore feature of Windows to restore your computer to an earlier time. That ought to undo any recent changes and eliminate the problem. Here are some additional solutions that you can try: http://answers.microsoft.com/en-us/windows/forum/windows_7-files/cant-create-anymore-new-folders-in-windows-7/721a9129-c800-4224-8779-805dd6dfb80e ( There are 3 steps ) Good luck, James
