  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:

  IF OBJECT_ID('TempDB..#holdforeachdb') IS 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
