In short
- Projects, in the sidebar after a scan, lists development projects untouched for 30 days that still hold folders tools can rebuild.
- Hibernate (Pro) moves those folders to the Trash and leaves a small marker in the project. Your code stays exactly where it is.
- Wake Up (free) runs each tool’s official install command in the project to bring the folders back. Undo also works, until you empty the Trash.
How to hibernate a project
- Scan the place where your projects live Scan My Mac, Home Folder, or choose your projects folder with Choose a Folder….
- Open Projects Click Projects in the sidebar. Each card shows the project, its path, the kinds of rebuildable folders, its last change and how much can be freed.
- Hibernate Click Hibernate. The rebuildable folders go to the Trash in one batch and the card shows how much was freed.
- Wake it up when you need it Click Wake Up on the card. MoreRoom runs the right install command in the project folder, then rescans.
Which projects appear
A folder appears in Projects when it hasn’t changed for 30 days and contains folders that tools rebuild on their own:
| Kind shown | Folder | Brought back by Wake Up with |
|---|---|---|
| npm dependencies | node_modules |
pnpm install --frozen-lockfile, yarn install --frozen-lockfile, bun install, npm ci or npm install, depending on the lock file |
| Python environment | .venv or venv |
uv sync, poetry install, or python3 -m venv then pip install -r requirements.txt |
| CocoaPods | Pods |
pod install |
| Flutter tooling | .dart_tool |
flutter pub get |
| Rust build | target |
Rebuilt by your next cargo build |
| Gradle cache | .gradle |
Rebuilt by your next Gradle build |
| Next.js build | .next |
Rebuilt by your next build |
| Unity Library | Library (Unity project) |
Rebuilt when Unity opens the project |
| build files | Other build folders MoreRoom recognises | Rebuilt by your next build |
If no project qualifies, the screen says No dormant project found.
Hibernate (Pro)
Click Hibernate on a project card. MoreRoom moves its rebuildable folders to the Trash in one batch and writes a small file, .moreroom-hibernation.json, in the project to remember what it removed. The card turns into a moon and shows the space freed.
Your source code, Git history and settings are never touched.
Wake Up (free)
Click Wake Up. MoreRoom runs, in the project folder, the official command listed above for each folder it removed — the tool must be installed on your Mac (Node.js, pnpm, Python, CocoaPods, Flutter…). When it’s done, the marker file is removed and MoreRoom rescans.
If a tool isn’t installed or its command fails, MoreRoom tells you what to run yourself: “Run in the project: …”.
Undo instead
Hibernation is a normal move to the Trash: until you empty the Trash, ⌘Z or History › Restore puts the folders back exactly as they were, without reinstalling anything.
