Different space quotas for different Windows users

Question

On Windows 7, is it possible to have set different disk space quotas for different users? How?

For example I'd like to limit my kids' disk usage to ~50 GB each, my roommate's to 100 GB, and so on.

Answer 1

You can partition the hard drive in the computer and then dictate access to the different drives with group policies. Unfortunately parental controls don't give the option of restricting different drives.

This also provides the benefit of knowing exactly where they are putting their files(in their lettered drive, possibly named after them) and lets you revoke their access to the windows system files which kids love to play around in.

Answer 2

Courtesy of @Uninspired and the Sevenforums, the answer is to dig past the first level of Quota dialog interface and use the [Quota Entries] button.
