So i got some files off a windows external HD and copied them to my new macbook pro. Most of the folders/files are fine. A few of the folders were invisible and when I show them I can view them and their contents fine on the mac. One or two of the folders however are dimmed out (like a shown invisible folder) but I can not open them. I double click and nothing happens. If I right click and do info it says I have read write access. I tried using chmod in terminal to update this and it still does the same thing. Why can't I access this folder?
