Win7. I have a folder on one of my HDDs that was working fine when I had Linux installed but now that I have reinstalled Win7, the folder shows empty (no big deal) and when I try to delete it, it says it can't because it's not found. (I swear. It's RIGHT THERE. I can see it.

) I can't move it, rename it, add or subtract anything to it. I get the same error message every time. I've tried enabling unrestricted/super administrator privileges but still can't delete it as the computer still thinks it's not there. I've rebooted, too.
EDIT: I just realized there's a colon (

in the folder name (which was allowed under Linux but not under Windows). I can't rename the folder to get rid of the colon. Might or might not be the problem?
How can I delete this folder?
