Google Takeout saves emails in mbox files. These files are based on the generic mailbox format but use a proprietary format for message status information (unread, deleted, etc.). Aid4Mail 5 will recover emails status information and it can re-create the folder structure of the Gmail account.
In order to process a Google Takeout export, simply select "Google Takeout" as the source format under "Source", then select the mail folder or file from the Google Takeout export under "Location".
