Mod Organizer 2 Overwrite & Logs Folders (MO2)

Bottom Line: It is 100% safe to clear MO2 logs and unneeded temporary files in overwrite. Clearing log files will NOT delete installed Skyrim, Fallout 4, or Starfield virtual mods in Mod Organizer 2.

What are MO2 Overwrite & Logs Folders?

Located inside your Mod Organizer 2 directory at Mod Organizer 2/overwrite and Mod Organizer 2/logs, these folders are managed by Mod Organizer 2 (MO2).

MO2 uses:

• overwrite/: Catch-all folder where virtual mod tools (FNIS, Nemesis, BodySlide, ReShade, SKSE logs) write output files generated during mod configuration.
• logs/: Plain-text diagnostic logs recording virtual file system (USVFS) hooks and mod load orders.

Over time, MO2 log files expand, consuming 1 GB to 5 GB of storage.

Can You Delete MO2 Overwrite & Logs?

✅ Yes, log files are 100% safe to delete.

• Safety rule for overwrite/: Create a new mod from overwrite in MO2 (Right-click Overwrite > Create Mod…) to preserve BodySlide meshes or FNIS animations before clearing overwrite.
