FSRM

A Windows Server role service for managing storage through directory-level quotas, file screening, and automated data classification.

FSRM provides granular control over Windows Server storage environments. Use it to enforce hard or soft quotas (like a 500 GB limit on department shares), block specific file types (such as .exe or .mp3) via file screens, and automate data management with the File Classification Infrastructure (FCI). It is a vital tool for preventing disk-space exhaustion and ensuring compliance by identifying sensitive data across volumes. Admins can trigger custom scripts or email alerts when thresholds are hit: a proactive way to maintain server health without third-party overhead.
