By default, Windows Explorer hides the extensions of file types it recognizes (.EXE, .PNG, etc.). It's important that these be visible when setting up mods or asking for support, so we will make sure Windows always shows file extensions for all file types.
- Open a File Explorer window (it doesn't matter where).
- Click the View button at the top of the window.
- Click Show > File name extensions.
- Open a Windows Explorer window (it doesn't matter where).
- Click the View tab at the top of the window.
- Check the box labelled File name extensions if it is not checked already.
File extensions are automatically shown in SteamOS Desktop Mode.

Sounds good. Move onto the next page.
Be aware that some of your mods may not be compatible with OMO CEP.
You will need to reset your game files before continuing.
- Open your OMORI\www folder.
- Back up the save folder inside by copying it to another location on your computer.
- Delete every folder inside the www directory except the folder named save.
Make sure not to delete the save folder!
It contains your save data, and OMORI does not have cloud save support!
