Hey! Having a very strange problem with my 4GB Stig Memory Stick ... there's a folder on it that had 2 small pdf files (for college) that now says it's 54.5GB. Within this folder are other folders and files that my laptop can't read. They have nonsense names on them ... literally random letters and numbers. I've tried deleting the whole file, deleting individual files (within the folder) & formatting the whole drive. It's causing problems with some other files (mainly .avi files) ... sometimes they work, sometimes they don't so can't be totally sure that it's related but call it an educated guess. Any ideas?? I wouldn't be totally clueless when it comes to computers but i've never seen this before! Thanks!!
