First, I'd evaluate if you really need to keep all of the papers you are filing. Sometimes we hold on to papers we may never need to go back to or perhaps the information is easily retrieved elseware, like online.
As far as the rest of the papers you are filing, I'd really work on filing catagories with sub-catagories. You may still have a lot of files, but you will have an orderly system of retrieval. Hint: Think "retrieval" when setting up your catagories.
