I have copied(with 'pathfinder) a big-sized folder from a network pc to my mbp external hd. The problem is that I cannot see the contents of neither folders using finder. They are displayed in gray (shaded). But, this seems to be a finder problem. 'Pathfinder' file explorer, can display all items of the folder and I can open any file. I should tell that the folder is quite big, about 50gigs. But I cannot understand why Finder do not browse the contents. Can you please help me solve this problem?
