Cannot delete / ignore folder - keeps telling me I need to clean up

I have decided to remove the bin folder from one of my web apps from Sour开发者_如何学Goce Control. It contains only external dlls which are stored in another folder anyway.

I right click and choose 'Delete and add to ignore list' but the error message below:

Directory 'C:\Kctc\Trunk\Moose\Bin\de is missing Directory 'C:\Kctc\Trunk\Moose\Bin\de is missing Please execute the 'Cleanup' command.

I can choose Cleanup on both the bin folder and the overall working copy folder and it tells me the process was successful, but when I try the 'Delete and add to ignore list' again I get the same error message.

Delete the whole working copy (e.g. rd /s /q ) and then checkout a new one.

If you have local modifications, copy those files out first, and then copy them into the new working copy.
