Commands

BOOT

Will start floppy images or hard disk images independent of the operating system emulation offered by DOSBox. This will allow you to play booter floppies or boot other operating systems inside DOSBox.

CD (Change Directory)

Allows you to move up and down a directory tree. CD is simple to use, just type

CD [Directory-Name]

And if the Directory-Name correctly refers to an available directory then you will be moved from your current working directory to the new one. Once completed, any command you issue will operate under the new working directory, and your prompt will be updated to reflect your current working directory. Multiple folders can be traversed at once (assuming you know the correct names) by typing their names together with the \ separating them for example

C:\>CD SIERRA\KQ5
C:\SIERRA\KQ5>

There are also 3 special directories that are available inside every directory which help you simply move around. They are

.        which refers to the current directory 

..       which refers to the directory directly above the current directory

/        which refers to the root directory

Once you have moved into a sub directory, you can move back by typing

C:\SIERRA\KQ5>CD ..
C:\SIERRA>

And like all other directories you can string them together

C:\SIERRA\KQ5>CD ..\..
C:\>

If you ever need to move back to the root directory you can use the \ alias.

C:\SIERRA\KQ5>CD \
C:\>
