+## FAQ
+
+**Q: Will Mole delete important files?**
+A: No. Mole has built-in protection and skips system-critical files.
+
+**Q: Can I undo cleanup operations?**
+A: Cache files regenerate automatically. For uninstalled apps, use Time Machine backup beforehand.
+
+**Q: How often should I run cleanup?**
+A: Once a month is sufficient. Run when disk space is low.
+
+**Q: Is it safe to use?**
+A: Yes. The tool previews what will be deleted before any action (`--dry-run`).
