There are some applications that allow you to make your Boot Camp volume bigger. The best app is Paragon Camptune > http://www.paragon-software.com/downloads/camptune.html Make a backup of your data before using it.
If you don't want to use that app, the only way is to delete your Windows volume and create a bigger volume on the hard drive

You could consider using an external drive and an Windows Mount Point to make the external drive look as if it is a directory on your C: drive. I used to use that technique all the time on my old Dell laptops running Windows 2000 or newer. Just keep in mind that if you do this, you will always need to connect the external drive before you start Windows, otherwise critical files might not exist on the system at load time, and things may not work properly.
You are probably better off using a tool like mende1 suggests.
