uMake has made it easy to make a duplicate file right from the File Manager.
To do this, simply tap and hold on any file to enter into the Reorder/ Edit mode. The files will shift position slightly to indicate they are movable or selectable.
Tap on a file to select it. A white outline shows that this file is selected.
At the top of the menu, tap on the duplicate icon (center icon) to make a duplicate file of the selected file.
A duplicate file will be created next to the original file.
To exit the Reorder/ Edit mode tap the white check mark in the upper right of the screen.
