HIER (File Format)
The HIER format is used to group logbook scans in Echoes into hierarchal categories, which are displayed while scanning objects. There is only one HIER file in Echoes, DUMB_ScanHierarchy in NoARAM.pak (asset ID 0xDD79DC2A). The hierarchy described in this file matches that in TREE, but is optimized for in-game scanning rather than pause menu navigation.
