I divide them into three piles based on tab orientation then place them alternately. Then I use the Staples labels and with the Staples Handy clear file boxes creating business and tax files. I can easily locate anything I need in a heartbeat. I also scan anything of importance into my computer before filing just in case I need to forward it. But keeping the originals in files is a falesafe in case the computer has a failure. I always say back up your backups--'Cause you just never know.
