Ocean Cleaner Idle Save File: Location & Backup Guide
Updated 2026-06-09

Where Is the Ocean Cleaner Idle Save File Located?
As a single-player PC title developed by Watt a Day Games, Ocean Cleaner Idle stores your progress locally. The save file is typically found in a dedicated folder within your user directory. Here is the default path:
C:\Users\[YourUsername]\AppData\LocalLow\Watt a Day Games\Ocean Cleaner Idle\
Inside this folder, you will see a file named save.dat or SaveData.sav. This file contains all your in-game progress, including collected junk, upgrades, and unlocked areas. Since the game does not rely on cloud saves by default, manually backing up this file is essential.
For a complete overview of the game's features, check our Ocean Cleaner Idle guide.
How to Back Up Your Save File
Backing up your save file ensures you never lose your hard-earned progress. Follow these steps:
- Navigate to the save folder path listed above.
- Copy the
save.datfile. - Paste it into a safe location, such as an external drive, cloud storage folder, or a separate backup directory on your PC.
We recommend creating a backup after each significant play session, especially before major system updates or reinstalling the game. For additional tips on managing your game data, see our resource management guide.
How to Restore Your Save File
If you need to restore your progress after a crash, reinstall, or moving to a new PC, follow this process:
- Close Ocean Cleaner Idle completely.
- Go to the save folder:
C:\Users\[YourUsername]\AppData\LocalLow\Watt a Day Games\Ocean Cleaner Idle\. - Replace the existing
save.datfile with your backed-up copy. - Launch the game. Your progress should be exactly as it was when you created the backup.
Always ensure the game is closed before modifying save files. Editing or replacing files while the game is running may cause corruption or loss of data.
Transferring Your Save to Another PC

save.datwith your transferred file. - Start the game to verify your progress.

Common Save File Issues and Solutions
You may encounter problems with your save file. Here are typical issues and fixes:
- Save file not loading: Ensure the file is in the correct folder and named exactly
save.dat. Check for file corruption by comparing file sizes. - Progress lost after update: Some updates may change save file formats. Always back up before updating. Refer to our patch notes guide for update details.
- Game crashes on load: This often indicates a corrupted save. Restore from a backup. If no backup exists, try verifying game files via Steam.
The developer, Watt a Day Games, may add cloud save support in future updates. Keep an eye on the official Steam page for announcements.
Why Manual Backup Matters in Ocean Cleaner Idle
Ocean Cleaner Idle is an incremental game where progress accumulates over many hours. Losing your save means losing all collected trash, upgrades, and ecosystem improvements. Since the game lacks built-in cloud saving, manual backup is your only safety net.
We suggest setting a recurring reminder to copy your save file every week or after reaching a new milestone. For more beginner-friendly advice, check our beginner tips guide.
