Genshin Impact & HoYoverse Output Logs (%LocalAppData%Low\miHoYo)

Bottom Line: It is 100% safe to delete Genshin Impact output logs and crash dump folders. Deleting log files will NOT delete your game progress, Primogems, Genesis Crystals, artifacts, or account credentials.

What are Genshin Impact Log Folders?

Located at %LocalAppData%Low\miHoYo\Genshin Impact on Windows, these files are created by Genshin Impact and HYP Launcher (HoYoverse).

The game client writes:

• output_log.txt: Session diagnostic log capturing Unity engine events, frame rates, and server connection status.
• Crashes/: Unity engine crash dumps created when Genshin Impact crashes due to graphics or memory errors.

Playing Genshin Impact or Honkai: Star Rail daily generates large text logs and crash dumps, consuming 1 GB to 8 GB of storage.

Can You Delete Genshin Impact Logs?

✅ Yes, it is completely safe to delete.

• Account data is cloud-saved: All your inventory, characters, and quest progress are saved on HoYoverse servers.
• Zero game file risk: Game binaries stay safe in C:\Program Files\Genshin Impact.
