Gmail Drive will actually send an email to yourself, with the files added to Gmail Drive to yourself. Gmail Drive will login to your gmail account, and perform search function to sort the files viewed in the drive. You may want to make a filter, for emails with prefix “GMAILFS” to moved to your archived mail folder.
Bare in mind, Gmail Drive will break if Google changes its new system. The developer might provides and update with new system. So, dont panic if the tool breaks, and don’t highly depends on the drive.
