It is not at all hard to take a screenshot in Fallout 76, all you need to do is press the PRINT SCRN button on the keyboard of your system. Mostly, the tricky part of taking a screenshot is that the users do not know where those screenshots end up. Fortunately, Save Locations is here to assist you and give answers to all of your questions. To get assistance with your operating systems, see below:
Normal Screenshot (with PRINT SCRN)
Screenshots taken with the PRINT SCRN key (not via Photo Mode) on Windows can be found at one of the following paths:
C:\Program Files (x86)\Bethesda.net Launcher\games\Fallout76
C:\Program Files\Bethesda.net Launcher\games\Fallout76
If both of those paths aren’t working, chances are, you’ve installed Fallout76 on a different drive or folder. Locate your installation files and you will find your screenshots!
Photo Mode Screenshot
If you’ve taken a screenshot on Fallout 76 via Photo Mode, you can find it saved in the following folder:
%HomePath%\Documents\My Games\Fallout 76\Photos
To go to this path, just open up File Explorer, go to your Documents, then My Games, then Fallout 76 and finally into Photos.
