Organizing and Archiving are two sides of the same coin. Organizing is the process of storing your digital assets in a way where they can be easily found and maintained. Archiving is the process of saving your digital assets to protect them from theft, hardware failures, or disasters.
Once again you should start within 24-hours on your archiving. Chances are good that if you wait longer than 24 hours then you will not start. Devote some time each day to organizing and archiving your files.
