There may be cases where you want to load .bom files (map files) directly into BoomBox without publishing them or downloading them in-game.
To load a .bom file into BoomBox, place it into your BoomBox/BoomBox_Data/Maps directory and the game will automatically unzip and load the map the next time the game is started.
You can also press F5 while the game is running and focused to have the game force reload everything in the Maps folder as well as unzip all .bom files found.
To manually load .bom files on Quest, you will need to use a side-loading application such as SideQuest to move files from your PC into your game folder on the Quest.
