I have a folder on my PC which is empty, but when I view its properties, it shows that it contains 3000 files of 577 MB. I made sure that there are no hidden files. When I copy this folder to a different location, it takes 3 minutes. Is there a way that I can view the contents of this folder? (I copied it to a memory stick and tried to view the contents on 3 differents PCs with different versions of Windows, but each time it shows that the folder is empty.)
