Please recommend see-through folders to buy. I am trying to clean and organize my space. Have lots and lots of papers, and I keep them in re-used folders and envelopes. I write on top of these folders and envelopes the contents This is quite cumbersome later on when trying to search for document(s). Just now I checked Amazon for see through folders and there are too many choices. I just want something simple that will fit a bunch of 8 1/2 by 11 inch papers. Please please help. Surely you organize your papers at home, try to keep things neat and tidy. Please guide me!!!
