Object type sorting is specific to object-related assets. Which is all assets in the Art folder and many in the Content folder.
The Assets folder on the GoogleDrive (and art repo) are organized the same as the Art folder on the game repo. First sorted by asset type, then by object type. Not all folders will have all types.
(The first 4 types in the list below are where 95% of common objects are kept.)
In-game objects that have 'life' per-se. This includes player races, animals/monsters, robots/borgs, and even vehicles.
In-game objects which can be picked up, stored on your character, or moved in a variety of ways (physics?). EX. bikehorn, bananas, guns, clothing, etc..
In-game objects which are too large to store on your character, most of which cannot even be picked up. EX. tables, chairs, plants, machines, etc..
In-game objects similar to furniture but are nearly exclusive to the structure of the station (tilemap). EX. walls (& wall mounts), floors, plenums, wires, pipes, etc..
