files with extension ".bytes": How do you make them?

[Keheck]

While researching a bit, I found out that the ".bytes" extension is a file type used by Unity and that the files themselves encode binary asset data. For ONI mods, this extension is used for animations amongst other things. Now I wanna know: How do you make these files? More specifically, how do you put meaningful data into these files?

I think this posts explains how it's done. Haven't tested though.
