Solved Specific folder loading very slow

I have a folder on my external harddrive that I have about 60GB worth of movies stored in. About a week ago I noticed that when I would try to open it, it would take a long time to load; I was and still am getting the green loading ribbon at the top. I can usually fix problems like this myself but this one has me stumped.

I have tried:
multiple virus/malware scans (all clean)
multiple sweeps with CCleaner
disk cleanup for the drive
defragging the entire drive the folder is in
turning off indexing
turning off thumbnails within the folder
changing the view to details; with no icons at all
using the classic folder view
changed folder template from Videos and Photos to All Items
also ran regsvr32 /u shmedia.dll

and there are probably a few other things I've tried over the past week with no luck at all. When I open the folder, it consistently takes over a minute to load everything. This is really getting on my nerves now, does anybody have any ideas or fixes for this? If its any help I started using Microsoft Security Essentials over AVG around the time it started doing this.

Vista Home Premium SP2 32-bit

Disable MSE and try then - just to make sure it is not MSE that causes the problem. Opening any 60GB folder on an external is of course a challenge.

I tried earlier today and it still takes a long time to load the folder. I haven't even added anything to it lately and before it would load everything instantly.

Have you tried putting the contents in a new folder?
Have you tested the hard drive?

WOW I made a new folder and moved everything into it and it loads instantly every time. I can't believe it was that simple, thanks for the help guys!

You are very welcome. That was just an old trick from experience.
