@ada alright then since TOC is definitely the top level of the whole structure, you could present the entire thing as a tree view with it as the root and referenced bundles as folders directly in it. probably the way to do it if you are going to mount the thing
this would obfuscate the fact that there's a difference between the first two layers and everything else; if you don't want that obfuscation, render as separate views, or in the same view but without packing them into one tree, preserving individual trees and showing associations between locations and table records. something like
INDEX BUNDLES
bundle1
#000 ├── flop.wav
#001 └── pearto.png
bundle2
#003 └── dialogue
bundle3
#004 └── meta
