Get Free Disk space using SQL Server

In order to programmatically determine Free Hard Disk Space using T-SQL, use the extended stored procedure master.dbo.xp_fixeddrives which returns a list of all hard drives and the free space(in MB) for each of the hard drive.

DriveNm char(1),
FreeDriveSpaceInMB int

EXEC master.dbo.xp_fixeddrives


Note: The T-SQL query shown above does not take into account Volume Mount Points. If you need to include mount points and monitor them, then make sure you check out this article CLR stored procedure to get disk space information which shows how to use a CLR stored procedure to return the capacity and free space of a mount point.
