You can also use SQL Management Studio to detach any database. To do so, Right-click on the Databases folder, and select the Tasks option and then select Detach.. from the context menu.
Clicking the Detach.. option will open the following window.
- Database Name: This will display the Name of the database that you want to detach.
- Drop Connections: Check mark this option to drop all the existing connections pointing to this database
- Update Statistics: Check mark this option to update existing optimization statistics.
Check mark the Drop Connections, and Click Ok

The above process will only detach the database from Server, but it will keep the Mdf, and ldf files within the physical location (C Drive)
