I find using the file foldes for filing and organising everything from bills correspondance to my colledge papers easy to do with the file folders combine them with the printable labes and you are in bussiness.
If I had realized how flimsy and cheap these things were I would have taken them back. But alas I had already split up the box so I have to keep them. I will probably donate them to work and purchase a new box. I've purchased Staples brand file folders before and they were fine I guess it's because these are the recycled ones need to check my old box of good ones to compare!
