Good Things Come to Those Who Collate

Case scenario: You need to quickly find a particular check in a large box filled with papers.

The most efficient way to do this is to use the "like with like" method.

Remove the papers in small batches. Begin by sorting these. This will keep you from becoming overwhelmed and you will be able to break away from this task at any time with minimal effort.
Begin collating items by type of document, for example: check stubs vs statements vs receipts.
Once you have your pile of checks you can collate them by the date, amount or source, whichever is easier for you to spot.
