empty sub-folders OSX

Hi all,
using a panasonic viera with powerbook 10.8.5
Everything worked fine then today I can "see" my mac on screen and the subfolders really spring up (as if they are not being scanned/read.) All the final sub folders are empty
Haven't upgraded the OS overnight so...???
Any help much appreciated
