Help with files from Fire Emblem Warriors: Three Hopes

[saselo]

I've been going through the data and file directory of the Fire Emblem Warriors: Three Hopes demo, and upon research can't seem to find anything about the file structure, which includes ".fdata" files, along with just ".file" files in another directory.

Would anybody know how to extract model data or just general data out of these, or is it something unknown for now?

I'm having the same issue.  Did you ever figure it out?
