If the user stores their email offline on their local hard drive, it is a good idea to create a backup copy of that email folder. A backup is especially useful if the hard drive crashes, or when the user wants to transfer their email to another computer. This document will discuss how to create a backup of the Thunderbird email folder.
The first step to creating a backup of the email folder is locating it. The default location is in your Hard Disk/Users/yourlogin/ Library/Thunderbird/Profiles/anoehcql.default folder. In the figure below, the window has been opened up to the location of the Mail folder.
If your Mail folder is not located here, perform a search on your local hard drive for anoehcql.default. Click on anoehcql.default in the results to see the path to its location.
The Mail folder is the folder that you need to back up. Place a copy of this folder on external media (CD, floppy disk, zip drive, etc.) or place it on a secure server if you have access to one.
