On your main drive, unlock hidden files.
Navigate to the Users folder and locate your computer's name. Open it and find the 'AppData' folder.
Inside 'AppData,' you should find a folder named 'Another Eden.' Copy this folder.

When transferring the data from Steam to your mobile device, delete the original 'Another Eden' folder. When you're ready to transfer the data back to Steam:

1. Open Another Eden on Steam.
2. Log in to your account when prompted.
3. Instead of downloading, close the program.
4. Navigate to the 'AppData' folder, delete the newly created 'Another Eden' folder, and replace it with your backup.
