File Manager is the most important app on your phone. It should be on one of your Home Screens. The icon is an open folder with a little green android on it. Touch this to open File Manager and review all your user folders and files. Downloads will usually be in the folder marked downloads. You can create folders, move files etc by using your Menu icon, which is a hard or soft icon consisting of a number of horizontal lines arranged to give the appearance of a menu.
If you do not have a File Manager icon on any of your Home Screens, then look for a hard or soft icon which has six small squares arranged like a waffle. Touch this to see your apps. Swipe sideways or up and down to see more apps. One of these should be your File Manager.
To get home, touch the Home icon, which is a waffle made of four squares.
You may need to get a stylus for poking with. A ball-point pen with cap on may be used.
Hope this is helpful.
