OS (C:) vs DATA (D:)

Hi everyone.

What is the difference between the OS (C:) vs DATA (D:) drives on a laptop. Are they for different things? Can D not be used for games and things like C? Why is D so much larger?

In the old days, computer manufacturers didn’t have a way to easily name drives the nice descriptive names that they do now, so they used letters.

* Typically “A” was for floppies.
* Then “B” was for a second floppy, or backups.
* When hard drives became common, “C” became common for hard drives.
* When CDs became common, “D” was used for the type of drive that could read CDs.

Et cetera, et cetera.

By default, Windows will just use the next available letter after “C” for any new drive it sees, but nowadays, you can assign other drive letters if you don’t want to use the defaults.
