USE master;
MODIFY FILE (NAME = master, FILENAME = 'D:\Data\master.mdf');
MODIFY FILE (NAME = mastlog, FILENAME = 'D:\Log\mastlog.ldf');

–> Right click on service and goto property.
–> Goto startup parameter tab and select “-dC:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\DATA\master.mdf”
–> change it by “-dD:\DATA\master.mdf” and click on update.
