### 3. Drives and Directories

#### 3.1. Changing Drives

If you have different hard drives or partitions, you may need to change to another drive. If you are on drive C and you want to move to drive D you can type:

d:

at the prompt and press <ENTER>. You will now continue on drive D.  If you have another drive, it is recommended not to use drive C, because it contains your system files. In these exercises in the online DOS emulator, however, we'll use the C-drive only, it doesn't have other drives.
