Many of us create a new document, spend considerable time & effort updating it, but only save our work at the very end. A system crash or other computer problem can render our hours of work lost forever.
A simple trick employed by the pro’s is to save your work early & often. As soon as you start, save it to the appropriate folder using a logical file name. If you’re creating multiple drafts, consider using the date at the end, such as 010607. You can separate different versions on the same day by using letters, such as 010607A, & 010607B. Then, when you’ve completed the final draft you can save if without the date & delete all earlier drafts. Remember Murphy’s Law when it comes to saving your data; “If it can go wrong, it probably will!”
