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.

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

===Skybox mipmaps===
===Skybox mipmaps===
Those gaps occur in every level after each of the 5 skybox textures. They're filled with zeroes. Their size matches that required to store MIP map generations of the preceding [[TXMP]] chunk.

A few of those in level 0. Reauthored duplicates of existing OSAm/OSGr pairs: for every pair, there are (minor) changes either in the OSAm or in the OSGr.

===Language versions===
Most localized (non-English) versions of Oni have new speech dubbed in. This will result in large differences in the SNDD files and SUBT for level 0.

===Texture compression===
===Texture compression===
Textures ([[TXMP]]s) can be stored with compression, and the amount of textures which are compressed in a given version ranges from "most" to "almost none". This leads to dramatic variations in size for the .raw (over 10% of the total amount of game content).

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.
