I looked at the image but can you confirm these folders are on the Root Directory? EG on the C:\ drive, and not in any other folders?
If so, they are certainly strange. Anything inside them?
Are they 'hidden system' folders? If you go to the Control Panel, then Folder Options and the View tab, have you unchecked the option to "Hide protected operating system files (Recommended)"?
If that option is still checked then I would say they are not Windows folders at all, (not placed there by Microsoft).
Have they always been there?
Another little pet peeve of mine is wasted space. Not that it matters when you have a 500GB drive on a laptop but I have all these folders in my root of the system drive that I'm not sure even need to be there.
I learned a long time ago not to delete stuff arbitrarily but I would like to know just how important these folders are. They all have these very cryptic names which look like long hexadecimal numbers. I am going to try and provide a link to a pic of them here --> http://www.flickr.com/photos/59976690@N03/5545901727/ <--
I would like to zap them but I was hoping someone here knew a little more about them first. Any ideas?
