# Storage and migration [Back to AI agents & app data](https://rustic-game-engine.pages.dev/markdown/guides/ai-agents.md). On Windows the location is normally `%LOCALAPPDATA%/RusticEngine/RusticGameEngine/data/editor/agents`. `projects/` separates projects using the canonical project path; `user` holds shared integrations. Trust `workspace_info.agent_directory` for the actual project location rather than calculating a hash yourself. Opening an older project transfers Rustic's plugin and Claude skill, including edited files, into app data. Generated `AGENTS.md` and `CLAUDE.md` move as well. Rustic removes only its own registration from shared project MCP and marketplace files. Other plugins and user-owned instruction files stay in place. If both locations contain different versions of a file, migration keeps the old file in the project as well as the app-data version; compare them before removing either. Empty integration directories are removed after migration.
