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, <code>DUMB_ScanHierarchy</code> in <code>NoARAM.pak</code> (asset ID <code>0xDD79DC2A</code>). The hierarchy described in this file matches that in [[TREE (File Format)|TREE]], but is optimized for in-game scanning rather than pause menu navigation.

=== Node ===
Each node represents either a Category, a Scan, or an Option. When scanning a logbook scan, the game locates its node and all its parents, and displays up to 5 Categories as well as the Scan node.
