If You are running an Online Work at home Business it is very critical that you create a well organized directory structure.
The Obvious advantage of an organized Directory structure is it makes it easy to find what you need.
A Less Obvious but More Important Reason is it makes it easy to back up your Online Business Files if they are all in the Same Place.
A very Simple Directory Structure for an Online Business Mimics a File Cabinet.
You would have 3 Level of Directories.
Your Top level would be the File Cabinet, Your 2nd Level would be the File Drawers and your 3rd Level would be your File Folders.
Step 1 (File Cabinet) Decide where to place your Top Level Online Business Directory.
I suggest creating a Directory Directly under My Documents called My Online Business.
You may want to think of this Top Level Directory as a File Cabinet with many Drawers Step 2 (File Drawers) Decide what are your 2nd Level Directories (The Drawers of your File Cabinet).
Here are some of my 2nd Level Directories or Drawers

• My Programs
• My Downloads
• My Income and Expenses
• My Text Ads
• My HTML Ads

Step 3 (File Folders) Decide what are the 3rd Level Directories or file Folders Here is what a Finished Directory Structure Might Look Like

• My Documents
• My Online Business
• My Programs
  • My Ad Trackers
  • My Domains
  • My E-mail Accounts
  • My Free Programs
  • My ISP Accounts
  • My Moneymakers
• My Downloads
• My Ebooks
• My Programs/EXEs
• My Zips
• My Income and Expenses
• My Income
• My expenses
• My Text Ads
• My HTML Ads

Now when you want to backup your Business Files all you need to do is copy yourOnline Business Directory to tape, CD, DVD or some other back-up Device.
