With Windows 2000, you can track and control disk space usage. You can configure Windows to:

Prevent further disk space use and log an event when a user exceeds a specified disk space limit.
Log an event when a user exceeds a specified disk space warning level.

When enabling disk quotas, you can set two levels: the disk quota limit and the disk quota warning level. The limit specifies the amount of disk space a user is allowed to use. The warning level specifies the point at which a user is nearing his or her quota limit.

If you want to track disk space use and do not want to deny users access to a volume, enabling quotas and not limiting disk space. You can also specify whether or not to log an event when users exceed either their quota warning level or their quota limit.

When you enable disk quotas for a volume, volume usage is automatically tracked for new users from that point on. However, existing volume users have no disk quotas applied to them. You can apply disk quotas to existing volume users by adding new quota entries in the Quota Entries window manually.

Note: 1. the quota is used on a per-user basis.

2. The users won't receive the warning when they reach the warning level. Warning is jut for the administrator to track the space usage.

3. Administrator won't and shouldn't be limited.
