Netscape 7.x and Mozilla mail (if you use Thunderbird, see directions below):
Step 1: Quit out of Netscape (or Mozilla)
Step 2:. Open “My Computer” and go to Tools->Folder Options->View and indicate that you want to Show Hidden Files and Folders.
Step 3: Find the .slt folder for your Netscape/Mozilla profile. The path toward finding it should look something like this C:\Documents and Settings\<your username here>\Application Data\Mozilla\Profiles\default.
Step 4: Right click on that .slt folder and choose Copy
Step 5: Navigate to your personal Users folder. Once you’re inside it, go to Edit->Paste. Replace if prompted.
Thunderbird mail:
Step 1: Quit out of Thunderbird.
Step 2:. Open “My Computer” and go to Tools->Folder Options->View and indicate that you want to Show Hidden Files and Folders.
Step 3: Find the .qfm or the .default folder for your Thunderbird profile. The path toward finding it should look something like this C:\Documents and Settings\<your username here>\Application Data\Thunderbird\Profiles\
Step 4: Highlight that default folder. This is the folder you want to save on a CD or zip drive in order to back it up. (Since network space is tight, we ask that you do not back your email up to your Users folder.)
Step 5: If you want to back your folder up to a CD and you have a CD burner in your computer, then follow these directions
Step 6: To copy your mail folder to a zip drive, just right click on the folder from Step 4 and choose copy. Then go to My Computer->your zip drive and click on Edit->Paste.
