The last time I had anything even approaching that problem, it was a virus in the directory I was opening, but since you only have image files in there, I don't see how this can be the case.

The only other, somewhat far-fetched option I can think of, is that your drive needs a defrag, and that the contents of your effects folder is spread out all over the hard drive. That way, I guess it is possible, since NTFS uses tiny data 'blocks' to store data, that all that memory is being taken up by reference data. Nonetheless, it's bloody wierd that it should only happen to that one directory
