Get Data/Log File Names, Sizes, Percent Utilization--ALL DBs

,

This Stored Procedure Will Get:

- The Data and Log File Names

- The Data and Log File Sizes (MB)

- The Data and Log Percent Utilization (%)

for ALL Databases on a SQL Instance.

Numbers Should (More Or Less) Reflect What You See on The SQL

Enterprise Manager Taskpad.

LIMITATIONS: For Databases With Multiple FILEGROUPS,

it will only list information on one (the last)

FILEGROUP!

NOTE: Output Looks Best in Query Analyzer's "Results In Grid" Pane.

Tested On SQL 7 and SQL 2000.

But No Guarantees of Accuracy Made--Use At Your Own Risk!
