CurseForge & Overwolf Modpack Cache Folders

Bottom Line: It is 100% safe to clear the CurseForge app cache. Clearing the cache will NOT delete your installed modpacks (Minecraft, World of Warcraft, The Sims 4 mods) or custom save files.

What is the CurseForge Cache Folder?

Located at %AppData%\CurseForge and %LocalAppData%\Overwolf\Cache on Windows (or ~/Library/Application Support/CurseForge on macOS), this directory is created by CurseForge and the Overwolf application framework.

When you download modpacks or add-ons, CurseForge saves compressed .zip and .jar mod installer-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder)-folder) archives into its cache directory. Over time, as modpacks update, old archived zip files remain saved on disk, taking up 5 GB to 20 GB+.

Can You Delete CurseForge Cache?

✅ Yes, it is safe to clear.

• Installed mods remain working: Active mod files installed in game directories remain untouched.
• Auto-download on demand: If you reinstall a modpack in the future, CurseForge will simply re-download the latest mod version.
