I agree. IMO it should look like this:

+-------------------------------------------+
| Remove files from the database            |
+-------------------------------------------+
|                                           |
| You are about to remove %n files from the |
| database. Do you really want to do it?    |
|                                           |
| [ ] Also delete the files from disk.      |
|                                           |
