Where Are The Outlast Trials Save Files Located?
The Outlast Trials OPP save folder on Windows, what the odd folder name means, and how to back it up safely.
Last updated
The Outlast Trials stores saves under a folder called OPP, the internal project name, which is why searching for Outlast finds nothing. Inside sits the familiar Unreal split: SaveGames for progress, Config/WindowsClient for settings.
Steam Cloud covers these files, but co-op desyncs and reinstalls still eat progress often enough that a manual copy pays off. Back up the whole OPP folder with the game closed. Restoring single .sav files tends to fail because the slots reference each other.
Where The Outlast Trials stores this, by platform
%localappdata%\OPP\Saved\SaveGames
OPP is the internal project name, not a typo. Settings live beside saves in Saved\Config\WindowsClient. Copy the full OPP folder rather than individual .sav files.
Frequently asked questions
Why can't I find an Outlast folder in AppData?
The game files its data under OPP, its development codename. Paste %localappdata%\OPP into the Run dialog and you land straight in it.
How do I back up Outlast Trials progress?
Close the game, copy the entire OPP folder elsewhere with a date in the name, and pause cloud sync before any restore. Launch once after restoring to confirm your reagent and loadout are intact.
