In Windows XP, the directory of the file is ''local drive:\Documents and Settings\username\Application Data\Mozilla\Sunbird\Profiles\XXXXXXX.default\Calendar''. In Windows 95/98/ME the directory is ''local drive:\Windows\Application Data\Mozilla\Firefox\Profiles\xxxxxxxx.default\Calendar''. Note that the ''XXXXX.default'' is a folder with a random file name that helps suecure your data through its unpredictability. From there you should be able to simply copy-and-paste the file (CalendarDataFile.ics) to your preference of external media (extra hard drive, CD/DVD, flash drive, etc).
Methods of copy-and-pasting:
* Right-click the file, and left-click ''copy.'' Then go to the destination, right-click the white (lank) space, and left-click ''paste.''
* Left-click the file once to select it, then go edit->copy. Go to the destination folder, followed by edit->paste.
* Left-click the file to select it and use the key combination ctrl + c to copy the file, then go the the destination and press ctrl + v.
If something ever happens to your data, you can always reinstall Sunbird, then replace the default file (empty) with your backup file containing all of your data.
Hope this helps,
