What You've Learned
- Permissions are used to grant different access levels to your files and folders. You can share them as Read Only, or you can give users Read & Write access, or simply deny other users access to your files and folders.
- Mac OS X provides a common folder for all local users at /Users/Shared.
- Folder permissions and file permissions can be combined to limit access in very sophisticated ways.
