In a micro network, you can find out the disk quotas by opening the Properties of a disk drive, e.g. by right-clicking on the disk drive and selecting Properties from the shortcut menu.
Note! If the values in the Properties window are in gigabytes (GB), it is probably not the user's disk quota data but the utilization of the entire disk space, i.e. either the quota is not displayed correctly or there is no quota in use on the disk space.
