Trying to move a folder on site, but get following bad path error message ( see below ).

Looked on the file server and folder "..albums/2012/07_001" doesn't exist but "..albums/07_001" does.

Had a quick look on forum and couldn't see answer, but apologies now if i have over looked something obvious.

Regards Alex
