Use Marshmallow app data syncing feature to save folders in Feature Requests Posted June 28, 2016 · Report reply So I was thinking, as I flash my phone a lot, you guys could implement the new Marshmallow feature where Google syncs up to like 20 or 50MB of app data to their servers and store the folder keys there so when I install the app again it loads all my previous folders. Could be very convenient. Don't know about the security of that though... Encrypt it somehow with the device's IMEI? Or maybe check the device's IMEI and load previous folders found on the Sync servers. Just a thought, would be really convenient.
