This is a sub-page of Luigi's Mansion 2 HD.
Seemingly, this file identifies all objects in the game via hash IDs. Some of the hex in this file decodes to utter gibberish, but the majority of the file decodes to readable English. The words present must be the internal names given to the game's objects, placeable using level editing tools. Interestingly, this file wasn't present in the 3DS version. Why would it be needed in the Switch version? We are yet to find out.
