If you need to turn a physical document into a digital copy so you can easily send or manipulate it, then you'll need to follow these steps to easily scan it.

There's no need to use scanner apps before you upload an important document to Drive. Google's app can do that for you on both Android and iPhone.

If you want to try the same scan again, choose Retake. If you initiated the scan from the Browse screen of the Files app, you'll be asked to select a folder in which to save your scanned documents.
