Now that you know how to work with files, you'll probably soon be acumulating a lot of files. The files will be saved to your hard disk, and there are two very important facts about hard disks you'll need to be aware of.

• Hard disks can get filled with files, which can not only cause you to not be able to save files, but can also make Windows suddenly stop working correctly.
• Hard disks can break.

This tutorial will explain how to keep track of how much space your hard disk has and to make sure that it is managing your files efficiently.

A later tutorial in this series Backing Up Files will cover what to do to avoid losing your files in case your hard disk breaks.
