First, you'll need to log onto your computer as the Administrator, or as someone with Administrator privileges. Next, use your mouse to right-click a drive's icon in the My Computer folder. From the context menu that appears, select "Properties", then click the "Quota" tab of the "Drive Properties" dialog.
Now you're ready to enable Windows' quota feature. Just place a checkmark in the box labeled "Enable quota management". On this dialog you can also select the amount of space users are allotted, and when they should be warned they are nearing their limit.
Initially, the limit you specify here will apply to all users of this drive. But you can customize quotas, giving different each user his or her own disk space limit.
Just click on this window's "Quota Entries" button. You'll then see a list of all users authorized to access this computer, alongside their individual quota settings. Double-click a user's name, and you can adjust the limit and warning level of the selected user. You can even remove quota restrictions from especially responsible and privileged users, such as yourself.
What does this have to do with the new Drive Info program? Now, the program reveals whether quotas are supported on each drive. If so, it goes further, telling us if quotas are currently enabled, and reporting the current disk space limit and warning level for the current user. It even shows how close we are to filling our portion of the drive, by displaying the percentage of our quota that is already in use!
