+    Simple TempDB Files Move Script  
+    Purpose: Move TempDB files to new volume WITHOUT changing configuration
+    Author: Laurent Perroud
+    Date: 18.02.2026
+    
+    IMPORTANT: This script only moves files, keeps current sizes and growth settings.
+    SQL Server service restart is required after executing the commands.
