File folders are the foundation of your filing system, and file folders are not all created equal. Following are the details on the differences.

• Two-ply, reinforced, or double-top folders (same concept, different brands) should replace all your standard models. Two-ply folders cost a little more, but the reinforced tab that runs across the top of the folder, right where you grab it, can keep folders in good shape longer, saving you money by making them last longer.

Note: Have you ever noticed the parallel score marks that run along the bottom edge of file folders? This is where you're supposed to fold the folder to create a flat bottom as your file gets fat. Behold! The papers fit more comfortably in the folder and the front drops down to reveal the labeled tab in the back.

• File jackets are manila folders with closed sides (usually just one fold deep). Use these for small items that can fall out of regular folders, such as tickets or brochures.
• File pockets/wallets expand wider than jackets and serve well for standalone jobs such as a current project that may be toted to work or a meeting. Wallets can also turn your open shelving units, where hanging files can't be used, into first-rate filing real estate. Slip some file folders inside to keep loose papers from catching in the folders to keep loose papers from catching in the folds.

Note: Wallets don't fit well inside filing cabinets because their expandable sides can catch while you try to get them in or out. Buy plastic file wallets for longer use.
