Release unused space in SQL Server database
You can script the SQL commands that SSMS generates. Without us knowing what commands you execute, we don't have much to go on.
Also, pls be specific about each file and the file size. You have 12 files. How large was each file before the individual file shrink, and what was the file size after the individual file shrink?
Did you use the TRUNCATEONLY options of the DBCC SHRINKFILE commands? That is the default in the GUI.
Finally, no need to do a &quot;final&quot; DBCC SHRINKDATABASE. Work with each file separately instead.
