If you are wondering where the screenshots are stored, there are two different path depending on how the game is launched:
<aside> 1️⃣ Whilst playing in editor they are stored in
</aside>
YourProjectFolder → Saved → Screenshots → Windows
<aside> 2️⃣ And when you package the game and play it
</aside>
C:\Users\YourPCNameHere\AppData\Local\BeforeAfterCameraV1\Saved\Screenshots
to reach it manually:
You can open the start menu type %appdata% and press enter
You can then navigate one directory back by clicking Appdata on the address bar
And follow
Local → BeforeAfterCameraV1 → Saved → Screenshots
