What kind of paper clutter and why do you have it in the first place. If it is pictures, create an album. If it is newspapers tie them up and donate them to a recycling center. Create an area to sort and hold the clutter if it is something you want to keep. A bookcase maybe. My thing is do I really want it or will I use it? If I haven't used it in awhile I get rid of it.
I clean out my file cabinets every year during tax season. I go through receipts and if they are a year or more older I shred them. Same cancelled checks or items I don't need for taxes or other proof. Here are other ideas. (I buy large clear boxes with lids and store papers in there that are necessary I keep and place in the basement)
