This is the software publisher's description.

S.M.A.R.T. Disk Monitor automatically enumerates available networks and allows you to select disks to monitor and shares to iterate (admin access required). Disk utilization is polled via a Windows Service. Both warning and critical thresholds can be set. When the thresholds are crossed, S.M.A.R.T. Disk Monitor can send a detailed message, a PDA friendly message, or a user defined email message to any set of users. S.M.A.R.T. predictive disk failure notification enables Systems Administrators to receive notification before a disk fails. Off-line alerts can optionally be configured enabling Systems Administrators to receive notification when a disk is unavailable.

Numerous summary reports can be configured and scheduled. Results are emailed enabling IT managers to receive daily, weekly, or monthly summary reports.

Directories can also be monitored. Both warning and critical alerts can be set when a directory reaches a specific size. Directory size alerts are emailed. Systems Administrators can create their own HTML templates that include variable replacement tags. A different template can be assigned to each monitored directory enabling ISPs to notify customers of potential quota violations.

File extension reports enable administrators to monitor specific types of files.
