Whatever it needs to be - some have pdfs, images, schematics, code, text files with links.
If a text file starts getting too big I’ll reorder it or split it out.
I think the key thing is developing the skill that suits you - don’t try and constrain it with some rule (all files must have structure X) because invariably something will not fit that pattern and then you’ll give up or spend too much effort trying to find the holy grail of data structures and then you’ll give up.
Let it flow naturally without constraints, it will settle on a form that is useful
