Cannot copy file name: The path is too deep

Hello friends,

I operate a small wireless network at home between my laptop and PC. I often copy files from one computer to the other using Windows Explorer, drag and drop. No problems until the past two days. When I drag a file from one computer to the other and that file has any size to it, over 10 meg for example, I get this message after 90% of the copying is done. 

Cannot copy (File Name): The path is too deep.

Ever get this error “Cannot copy file_name: The path is too deep” when trying to drag-and-drop a file?

Or If you are getting a similar error copying to/from an external hard disk?
