The monthly 12 pocket expanding file is absolutely the best. I love to be organized, and I couldn't do it without these files. I use them at work and at home. I actually use them in combination with the 31 pocket daily expandable file. I put all my bills, flyers, birthday cards, and notes in the monthly files as I come across them. Then, each month, I take all the papers out the current month pocket and separate them in the daily folder . Each night, I pull out the next days papers, and I am ready to go.
