Query to Pull Database File Information

This query will list the name, size and location of all files for all databases. This is handy for checking and documenting database server configuration to confirm whether the server follows our recommended best practices.

set nocount on

declare @sql varchar(max), @sql2 varchar(max), @name varchar(100)

I’m sure that there are other ways to pull this data, however, in some environments your permissions may restrict you from using any method other than this to pull the data.
