Seeing the File in Device File Explorer
At the top of the Device File Explorer, there’s a drop-down you can use to select the 
device or emulator. After making your selection, the files appear in the main window. 
You can expand the directories by clicking the triangle to the left of the directory 
name.
Right-click the filename, and a menu pops-up that allows you to perform different 
operations on the file.
