This article will teach you how to manage your files by saving them to USB
​
From the App Drawer or home page, open ES File Explorer.
​

Find the document you want to select. In this case, it is a bunch of pictures of a coffee cup.

You should now see your document that we saved earlier. Hold your finger down on it until it's selected. You can press the tick box of other files to select more than one. Press Copy from the bottom of the screen.
​
​

Insert your usb, select from the sidebar and press paste to move the file across.
​
​

After that, all you have to do is wait for the file to copy across and you're done. You can now remove your usb with the files. You can now take the drive to the teacher's PC and print any of the files you want.
