I thought of something else you can. Check out this technet article...
You can:
If you want to set a custom disk quota for a user, click Quota Entries.
On the Quota menu, click New Quota Entry.
In the Domain\Name box, type "<domain>\<username>" (without quotation marks), where <domain> is the Windows NT domain on which the user has an account, and <username> is the user for whom you are setting a disk quota.
If you want the user to have access to an unlimited amount of disk space, click Do Not Limit Disk Space.
If you want the user to have access to a limited amount of disk space, click Limit Disk Space To, and then type the amount of disk space (in MB or KB). If you want a warning message to be displayed when the user is close to reaching his or her quota limit, click Set Warning Level To, and then type the amount of disk space (in MB or KB) that can be used before the warning message is displayed.
