Gmail will create a zip file and send you a notification email when it is ready. When you receive the email, click the link and follow the directions to download the zip file. (For your security, Google will require you to confirm your password.)
When you have downloaded your zip file, decompress the file and extract the contents into a new folder.
Inside the decompressed folder will be a folder called “Mail.” Inside the “Mail” folder you will find a file called “Production.mbox.” Drag and drop the “Production.mbox” file onto the Discovery Genie target.
