If you want to extract all the data from your collection for processing in an external management software or Excel table, this feature should be able to help you.
So to generate a .csv file from your collection, follow this process :
Press the MENU button on your remote control, and go to "Settings".
Then, in the second tab, scroll down to select "Generate a .csv file from the collection".
When you click on this option, a window will indicate "Current generation..." to inform you that the document has been sent to the email adress of your Zappiti account.
