Disk quota management
Updated: 04/26/2017 by Computer Hope

Alternatively called a quota, disk quota management are permissions given by administrators that set limits on the user, workgroups, or other groups of storage space. By setting a quota, this helps prevents a server or share from becoming full of data, but still allows users to save files.
Most users who send and receive e-mail or run a website may be familiar with quotas because of over quota messages, an indication they exceed their available space. Also, if an e-mail file attachment is too big to fit into the available quota you'll receive a similar error.
