I have just deleted 3 folders from a directory. 2 of the folders have been deleted and gone, the third remains. The delete completed successfully. I used shift-delete to avoid the recycle bin. Clicking on the folder gives 'Access is denied'. Programmatic tests show the folder "does not exist" but can't be created either.
This is on Windows XP 64-bit.
Does anyone know why this happens and how I can fix it? Will try a reboot but even if that works still interested in the underlying reason.
