On my computer, I have the PDF files filed mostly by the size of the block, if I don't have that info, I file by lap, full, etc., Christmas is labeled separately, paper piecing is separate and sorted by size of the block. On my word docs, I have them sorted mainly by size of the blocks, paper piecing. I'm sure that there are many different, more efficient methods of sorting, but this works for me. I would try some of the methods and see what works best for you.
