In Windows retail Oni, raw files (ending in ".raw") contain chunks of data which are indexed by instance files and loaded on demand. In Mac Oni and the Windows demo, separate files (ending in ".sep") contain some of the data formerly contained by raw files (see "Mac vs. Windows" below for details). Thus, data offsets given in instance files' instance descriptors may apply to a raw file in Windows and a separate file on Macs. | In Windows retail Oni, raw files (ending in ".raw") contain chunks of data which are indexed by instance files and loaded on demand.

The | The raw data is not packed as a compact sequence of 32-byte-aligned chunks. There are gaps of various sizes in every level, totalling 25 megabytes for the whole game. Those gaps seem to be the same across all versions, even if other content differs. The content of those gaps is detailed below. | ||

The following table illustrates how some data was moved from raw files to separate files after the Windows version was finalized. See [[History of Mac Oni]] for the reason why the Windows demo uses separate files like Mac Oni does. | The following table illustrates how some data was moved from raw files to separate files after the Windows version was finalized and before the Mac version was finalized.
