Setting up a Reference Filing System (A - Z)I have used a filing cabinet for over twenty years. Each drawer was full of dark green suspension files each clearly labelleled with short pieces of cardboard folded over to fit into the clear plastic tabs that snapped on to the files (and nearly impossible to remove later!). The labels were terse but all encompassing (Books, Mastercard, Medical, Music...) and each file contained at least half an inch thickness of paper.
This has all changed. I bought a box of 100 manila folders, removed the hanging files and replaced a small number of old files with about 150 manila folders, each clearly labelled and containing very specific information.
I have written an article about this filing system to help you set up a similar system for yourself, as well as a suggestion on implementing something similar for your email folders.
