Bags key
The ShellBags registry key holding per-folder view settings, indexed by the NodeSlot numbers referenced from BagMRU entries.
The Bags key sits next to BagMRU under ...\Windows\Shell. Its numbered subkeys (Bags\1, Bags\2...) correspond to NodeSlot values and hold the view state Explorer saved for a folder, typically under Shell or ComDlg subkeys with GUID-named children.
Paths are rebuilt from BagMRU, not from Bags. Bags matter in anti-forensics work: some cleaners delete BagMRU but keep Bags, leaving orphaned slots. See ShellBags limitations and anti-forensics.
