Is it possible to list information about the files (MDF/LDF) of all databases on an SQL Server?
I'd like to get a list showing which database is using what files on the local disk.
What I tried:
exec sp_databases all databasesselect * from sys.databases shows a lot of information about each database - but unfortunately it doesn't show the files used by each database.select * from sys.database_files shows the mdf/ldf files of the master database - but not the other databasesThis question is related to

just adding my 2 cents .
if specifically looking to find total free space only in Data files or only in Log files in all the databases, we can use "data_space_id" column. 1 is for data files and 0 for log files.
CODE:
Create Table ##temp
(
DatabaseName sysname,
Name sysname,
spacetype sysname,
physical_name nvarchar(500),
size decimal (18,2),
FreeSpace decimal (18,2)
)
Exec sp_msforeachdb '
Use [?];
Insert Into ##temp (DatabaseName, Name,spacetype, physical_name, Size, FreeSpace)
Select DB_NAME() AS [DatabaseName], Name, ***data_space_id*** , physical_name,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2))/1024 as nvarchar) SizeGB,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2)/1024 as decimal(18,2)) -
Cast(FILEPROPERTY(name, ''SpaceUsed'') * 8.0/1024.0 as decimal(18,2))/1024 as nvarchar) As FreeSpaceGB
From sys.database_files'
select
databasename
, sum(##temp.FreeSpace)
from
##temp
where
##temp.spacetype = 1
group by
DatabaseName
drop table ##temp
I am using script to get empty space in each file:
Create Table ##temp
(
DatabaseName sysname,
Name sysname,
physical_name nvarchar(500),
size decimal (18,2),
FreeSpace decimal (18,2)
)
Exec sp_msforeachdb '
Use [?];
Insert Into ##temp (DatabaseName, Name, physical_name, Size, FreeSpace)
Select DB_NAME() AS [DatabaseName], Name, physical_name,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) as nvarchar) Size,
Cast(Cast(Round(cast(size as decimal) * 8.0/1024.0,2) as decimal(18,2)) -
Cast(FILEPROPERTY(name, ''SpaceUsed'') * 8.0/1024.0 as decimal(18,2)) as nvarchar) As FreeSpace
From sys.database_files
'
Select * From ##temp
drop table ##temp
Size is expressed in KB.
You can also try this.
select db_name(dbid) dbname, filename from sys.sysaltfiles
I've created this query:
SELECT
db.name AS [Database Name],
mf.name AS [Logical Name],
mf.type_desc AS [File Type],
mf.physical_name AS [Path],
CAST(
(mf.Size * 8
) / 1024.0 AS DECIMAL(18, 1)) AS [Initial Size (MB)],
'By '+IIF(
mf.is_percent_growth = 1, CAST(mf.growth AS VARCHAR(10))+'%', CONVERT(VARCHAR(30), CAST(
(mf.growth * 8
) / 1024.0 AS DECIMAL(18, 1)))+' MB') AS [Autogrowth],
IIF(mf.max_size = 0, 'No growth is allowed', IIF(mf.max_size = -1, 'Unlimited', CAST(
(
CAST(mf.max_size AS BIGINT) * 8
) / 1024 AS VARCHAR(30))+' MB')) AS [MaximumSize]
FROM
sys.master_files AS mf
INNER JOIN sys.databases AS db ON
db.database_id = mf.database_id
If you rename your Database, MS SQL Server does not rename the underlying files.
Following query gives you the current name of the database and the Logical file name (which might be the original name of the Database when it was created) and also corresponding physical file names.
Note: Un-comment the last line to see only the actual data files
select db.database_id,
db.name "Database Name",
files.name "Logical File Name",
files.physical_name
from sys.master_files files
join sys.databases db on db.database_id = files.database_id
-- and files.type_desc = 'ROWS'
Reference:
If you want get location of Database you can check Get All DBs Location.
you can use sys.master_files for get location of db and sys.databse to get db name
SELECT
db.name AS DBName,
type_desc AS FileType,
Physical_Name AS Location
FROM
sys.master_files mf
INNER JOIN
sys.databases db ON db.database_id = mf.database_id
Using this script you can show all the databases name and files used (with exception of system dbs).
select name,physical_name from sys.master_files where database_id > 4
The query will error if multiple data files (e.g. ".ndf" file types) are used in one of the databases.
Here's a version of your query using joins instead of the sub-queries.
Cheers!
SELECT
db.name AS DBName,
db.database_id,
mfr.physical_name AS DataFile,
mfl.physical_name AS LogFile
FROM sys.databases db
JOIN sys.master_files mfr ON db.database_id=mfr.database_id AND mfr.type_desc='ROWS'
JOIN sys.master_files mfl ON db.database_id=mfl.database_id AND mfl.type_desc='LOG'
ORDER BY db.database_id
This script lists most of what you are looking for and can hopefully be modified to you needs. Note that it is creating a permanent table in there - you might want to change it. It is a subset from a larger script that also summarises backup and job information on various servers.

You can use the below:

Below script can be used to get following information: 1. DB Size Info 2. FileSpaceInfo 3. AutoGrowth 4. Recovery Model 5. Log_reuse_backup information
CREATE TABLE #tempFileInformation

DROP TABLE #tempFileInformation
Executing following sql (It will only work when you don't have multiple mdf/ldf files for same database)
SELECT
db.name AS DBName,
(select mf.Physical_Name FROM sys.master_files mf where mf.type_desc = 'ROWS' and db.database_id = mf.database_id ) as DataFile,
(select mf.Physical_Name FROM sys.master_files mf where mf.type_desc = 'LOG' and db.database_id = mf.database_id ) as LogFile
FROM sys.databases db
will return this output
DBName DataFile LogFile
--------------------------------------------------------------------------------
master C:\....\master.mdf C:\....\mastlog.ldf
tempdb C:\....\tempdb.mdf C:\....\templog.ldf
model C:\....\model.mdf C:\....\modellog.ldf
and rest of the databases
If your TempDB's have multiple MDF's (like mine have), this script will fail. However, you can use
WHERE db.database_id > 4
at the end and it will return all databases except system databases.
