com.facebook.horizon

User Settings​

The users settings for the Horizon app can be found in the /Android/Data/com.facebook.horizon/Horizon directory. The file settings-socialvr.xml contains the user's settings for the app.

Cached Assets​

The Horizon app caches its assets in many different locations, they are:

  • /Android/Data/com.facebook.horizon/cache
  • /Android/Data/com.facebook.horizon/files/downloaded_assets
  • /Android/Data/com.facebook.horizon/files/hz_asset_cache
  • /Android/Data/com.facebook.horizon/files/hz_asset_processing_cache
  • /Android/Data/com.facebook.horizon/files/hz_audio_file_cache

Only the cache directory contains files that can be opened and viewed. The other directories contain Unity asset files that require Unity to open.

These caches assets can be used to determine what worlds the user has visited and what assets they loaded. From my own analysis I was able to find assets from various worlds I had visited and assets from the Horizon app its self.

Worlds Visited​

JSON Path: /meta_horizon_worlds/worlds_visited.json

HTML Location Meta Horizon > Meta Horizon Worlds > Worlds Visited

Contains a list of all the worlds the user has visited on the Horizon app. Each entry contains some or all of the following information:

  • Description (String)
  • Name (String)
  • Achievements (Array)
    • Status (String)
    • LastUpdated (String)
  • Progress (Array)
    • Value (String)
    • Creaton Time (String)
    • Variable Name (String)

The JSON version also contains media files that are associated with the worlds visited. This seems to just be the world thumbnail.

Worlds Saved​

JSON Path: /meta_horizon_worlds/worlds_saved.json

HTML Location Meta Horizon > Meta Horizon Worlds > Worlds Saved

These files contain the same data as the worlds visited files but for worlds that the user has saved, it also adds a Saved On timestamp. It is to be noted that these worlds aren't necessarily saved by the user, they could be automatically saved by the app or suggestions on the home screen.

Worlds Progress​

JSON Path: /meta_horizon_worlds/worlds_progress.json

HTML Location Meta Horizon > Meta Horizon Worlds > Worlds Progress

Contains the same information as the worlds visited files but only for worlds that the user has made progress in.

Worlds Created​

JSON Path: /meta_horizon_worlds/worlds_created.json

HTML Location Meta Horizon > Meta Horizon Worlds > Worlds Created

Contains basic information about worlds that the user has created. This includes:

  • Name (String)
  • Accepted Roles (String)
    • Accepted Roles is always "World Owner" in my testing.
  • Invitation (String)
    • Seems to be the same as the Name field in my testing.
  • Updated Time (String)

Worlds Privacy Settings​

JSON Path: /meta_horizon_worlds/worlds_privacy_settings.json

HTML Location Meta Horizon > Meta Horizon Worlds > Worlds Privacy Settings

Contains the privacy settings for the user while on the Horizon app. The settings are:

  • Show Active Status Setting (On/Off)

com.fitxr.boxvr

Source: MTP

BoxVR is a VR fitness game that allows users to punch and dodge their way through a series of workouts. The game is designed to be a fun and engaging way to get fit and stay active.

Cached Assets​

The BoxVR app caches its assets in the /Android/Data/com.fitxr.boxvr/files/cache directory. The exact logic behind what is cached and when is unknown at this time and the cache is made up of .fitxr files. Each file starts with a type identifier followed by a UUID.

com.meta.curio.toybox

Source: MTP

Toybox is a demo application used to showcase the capabilities of the Meta Quest 3. The app allows users to interact with virtual objects and experiment with different features of the device.

Logs​

Toybox stores logs of which demos the user has played in the /Android/Data/com.meta.curio.toybox/files/ directory. The content of the logs is a lot of technical information that isn't particularly useful. The file name on the other hand contains the demo ran, the date and the time the demo was ran. An example file name would be FirstEncounters_Logs_25-01-17_14-12-29. This file name tells us that the user ran the First Encounters demo on the 17th of January 2025 at 14:12:29.
