You copy and paste the link for the file on a new tab, then you download the file. Once you have the file, go to the "draw anim" page. Click on the settings button (the gear) and then click the button that looks like a paper with a GREEN arrow. Then all your files should come up and you select the desired file. If you have the same device as me (Samsung Galaxy Tab A) then a thing will pop up after you click the green arrow asking what you would like to access. When or if this happens click documents and the files should come up
