CheckQuota is a powerful directory monitoring software that helps you stay in control of your disk space usage. It sends email alerts and can restrict write access for users or groups once a specific quota is exceeded.

Users can read and delete data, but they cannot copy new files or change existing data in the locked folder. When a user deletes data and brings the directory space under the specified limit, all write access is restored. CheckQuota offers a two-step mail alert system that notifies the user when the directory limit is reached and when write processes are locked. Users can also block specific file types for specific directories. For example, a system administrator can prevent users from storing MP3 or video files in their home directories.
CheckQuota comes equipped with a unique HTML report engine that generates clear HTML reports of directories. The reports show used disk space, the limit, and locking status, among other things. The reports can be published on the network so that everyone can view the status of the directories. Users can also send the status of their monitored directories via email. For instance, it is possible to notify users of their used directory space daily.
CheckQuota is essential for every system administrator and should be installed on every server. It is installed as a system service, meaning it runs on startup and operates without the need for users to log in. In conclusion, CheckQuota is a comprehensive and user-friendly program that allows system administrators to control and monitor directory size with ease.
