There is a non-sys. folder (just a folder w/ personal files & docs) that I can't seem to delete from the N900.

I get an error message saying that it cannot be removed, "file or directory is corrupted and unreadable."

Stranger still, this oddball folder is not even visible on the N900 file manager. I can only see it when browsing files w/ it connected to my Windows PC.

I've done some searches here and w/ Google. There isn't too much I found in the forums on this topic yet. From elsewhere, though, clearly this is a not uncommon PC problem, but I wonder how to handle it when on a device like the N900?

Thank you for any help.
