| Tip |
|---|
BEFORE making any changes to the file, it is recommended that you back this up and place it in a different location. |
It’s also worth noting, if you are emailing these files , you may need to stop the Yellowfin service (especially on Windows) as it will either not allow you to send, or send blank files.
