Oni (folder)

This is a browseable representation of an Oni installation's file hierarchy under Windows and macOS. You can use it to verify that you have all the needed files; it can also educate you on the details of what each file does and how Oni finds its game data. Click on a folder's name to go down to that level of the hierarchy; click on a file's name to read more about that file.

Installation location

The default location for this folder in Windows is C:\Program Files (x86)\Oni\ – it was originally C:\Program Files\Oni\ on 32-bit systems, but modern Windows has a hack for old program installers which changes Oni's installer to point to the x86 folder by default. The Russian localization's installer adds another level with the publisher's name: C:\Program Files (x86)\Buka\Oni\.

There is no default location on Macs because modern Macs cannot run the installer on the CD-ROM, and so users must drag the "Oni ƒ" folder manually to their hard drive.

Warning for non-admins

If you are not logged into Windows as an administrator, Oni will save persist.dat, debugger.txt, key_config.txt and startup.txt in C:\Users\<username>\AppData\Local\VirtualStore\Program Files\Oni\. This does not apply to an installation of the AE or a manual installation of Oni. Right-clicking Oni.exe and choosing "Run as administrator" will cause Oni to save the aforementioned files in the Oni folder itself. However this will mean you have two save-game files, with either one being written to depending on whether you run Oni as admin or not.

Directory

Legend
= needed to run Oni; = created by Oni; = unneeded files

Your initial Oni installation will probably have all the red and blue files. For files marked with yellow, Oni may not have seen a need to create them yet (follow that file name's link for more info).
