Do you really need a filing cabinet full of old bills, paychecks, and receipts? If they are no longer needed, dump them. If you have receipts for tax purposes or warranties, they need to be stored somewhere (although many people these days are scanning them and saving on a hard drive). You should save paychecks from the past two years; throw the rest away (scan them first if you must). And bills, who needs them? If you can, sign up for electronic bills and paychecks to save the environment.
