Running out of disk space is one of the most disruptive events a DBA can face: it halts log backups, prevents transactions from committing, and can take databases offline. This script, adapted from the DBA-Scripts collection by Bulent Gucuk, reads allocated file sizes from <code>sys.master_files</code> and joins to <code>sys.databases</code> to produce a single server-wide size report. It runs from the master database, requires no cross-database queries, and takes milliseconds to execute — making it safe to run at any time, including during a production incident.</p>
