Can I remove "pictures" folder?

I have tagged a bunch of pics (I actually meant to make them files in the gallery, but couldn't figure out so I tagged them instead.
So, now I have a list of tagged galleries, along with the original pics in the picture folder at the top of the box.
I also seem to have gotten a group of pic files in the folders file towards the bottom of that box which are also dupes.
So now I have 3 sets of my pictures in different places in Windows Photo Gallery.
I'd like to delete 2 of the sets and just keep the tagged set if possible.
Seems when I delete the pics from the pictures files, it deletes all my pics.
Any help will be appreciated.
Thank you.

Unless it says 'copy of filename' then it likely isn't a duplicate. There is actually more than one way to get to the same files in 'My Documents'.
