If you don’t already have a stock file manager app on your device, you can install one from the Play Store. Here you can find plenty of free and paid file managers.

If you want to exit a folder, tap the back button on your device, or on your screen.

On most devices, you can select more files to transfer after you highlight the first one.

On some devices, you may see three vertical dots or three horizontal lines instead of the More button. In this case, tap this icon.
