I want to backup the Mezzmo database just in case I should lose my hard drive. Based on another post on the forum, I've found the Mezzmo database location but I'm looking for a little clarification on a couple of things.

1) What files do I need to backup in the C:\Users\%user%\AppData\Local\Conceiva\Mezzmo folder in order to recover the database? Do I just need the Mezzmo.db file or should I backup all of the *.db files in this directory?
2) There is a folder named 'TranscodingFiles' located in the Mezzmo directory, which is currently around 22 GB in size and currently has 4 sub-folders located within. 3 of the 4 sub-folders were created prior to January of this year and the last one was created 2 weeks ago. Do I need to backup the 'TranscodingFiles' folder in order to recover my Mezzmo setup? What is this folder being used for and can I delete the older folders and just keep the most current one that was created two weeks ago?
