Change location of saved scenes
Discuss this topic at Factory I/O Community Forum
The default location for saved scenes can be changed by defining it in an auto.cfg configuration file.
Create a file named auto.cfg by using a text editor (Notepad will do the trick) and add the following line: scene.my_scenes_path = r"C:\My Scenes\" (replace the path by your own). Next, place this file in 'C:\ProgramData\Real Games\Factory IO'.
More information about the auto.cfg file and its contents can be found in the Console section of the manual.
