Give your files a green makeover! Organize and de-clutter the office by creating portable document files (pdfs) of all your bills, contracts, and receipts on your computer. Keep the files on your hard drive, or move them into usb flash drives that you can store elsewhere for safe-keeping. You'll be saving trees since all your files are now in a digital format. Send documents and expense sheets to your accountant or financial planner via email instead of printing them out. You'll also be able to find information quicker than looking for missing folders at the back of your desk.
