Introduction to Quotas While system hardware prices have steadily declined, disk storage is always a limited resource. A more effective strategy is therefore to manage and control the existing storage. Disk Quotas are implemented in many operating systems and are an essential tool for the maintenance of operating systems. Disk Quotas control disk space consumption by users and directories and prevent any single user from consuming all of the disk thus preventing system crashes. Quotamanagement systems control the changes in disk space allocation (save, move and delete files) of users, disks or directories. Neither does Windows NT nor does Windows 2000 have such a feature. Several software companies have developed disk quota-management tools but, unfortunately, they are very expensive. In order to improve the performance of our Windows- NT-network we have also developed our own intelligent user quota monitoring system. It has been realized with just some APL2programs and works closely together with a client-server-datebase. 2. Basic ideas At APL Berlin 2000 I showed an optimized parallel program which was fast and good enough
