Great script, thank you! I think you meant for this line:

RIGHT(FileName,CHARINDEX('',REVERSE(FileName))-1) PhysFileName

to be

RIGHT(FileName,CHARINDEX('\',REVERSE(FileName))-1) PhysFileName?

here is the updated script:

-- Get database file information for each database

IF OBJECT_ID('TempDB..#holdforeachdb') IS NOT NULL

DROP TABLE #holdforeachdb;

create table #holdforeachdb

( [databasename] [nvarchar](128) collate sql_latin1_general_cp1_ci_as not null,

[int] not null,

[name] [nvarchar](128) collate sql_latin1_general_cp1_ci_as not null,

[filename] [nvarchar](260) collate sql_latin1_general_cp1_ci_as not null

)

INSERT

INTO #holdforeachdb exec sp_MSforeachdb

'select ''?'' as databasename,

[?]..sysfiles.size,

[?]..sysfiles.name,

[?]..sysfiles.filename

from [?]..sysfiles

WHERE db_id(''?'')>4'

--NEW location of DB files

DECLARE @NewDataPath NVARCHAR(4000)='N:\datafiles\DBDATA\', /*!!!!!!MODIFY ACCORDINGLY!!!!!!*/

@NewTlogPath NVARCHAR(4000)='L:\datafiles\DBLOG\' /*!!!!!!MODIFY ACCORDINGLY!!!!!!*/

;WITH DataBasefiles (dbname, size_Gb, logical_name, Path, PhysFileName, FileType)

AS

(select databasename ,

(size*8.00/1024/1024) size_Gb ,

sf.name logical_name,

LEFT(FileName,LEN(FileName)-CHARINDEX('\',REVERSE(FileName))+1) Path,

RIGHT(FileName,CHARINDEX('\',REVERSE(FileName))-1) PhysFileName,

SUBSTRING([filename], (LEN(filename)-2), 4) AS FileType

from #holdforeachdb sf

JOIN sys.databases db on db.name=sf.databasename)

/***DON'T FORGET TO MOVE DB FILES TO THE NEW LOCATION BEFORE RUNNING ALTER DATABASE DB SET ONLINE;****/

select dbname,

--size_Gb,

logical_name,

Path,

PhysFileName,

FileType,

CASE

WHEN FileType = 'ldf' THEN 'USE [master]; ALTER DATABASE '+'['+dbname+']'+' SET OFFLINE WITH ROLLBACK IMMEDIATE;'

ELSE '' END AS 'SET_DB_OFFLINE',

'USE [master]; ALTER DATABASE '+QUOTENAME(dbname)+' MODIFY FILE (Name = '+logical_name+' , FileName = N'''+CASE

WHEN FileType = 'mdf' THEN @NewDataPath

WHEN FileType = 'ndf' THEN @NewDataPath

END +''+PhysFileName+''');' AS 'MOVE_DB_FILES_CMD',

CASE

ELSE '' END AS 'SET_DB_ONLINE'
