Hi,
SQL 2008R2
Added four new equally sized .mdf files to a production tempdb last night and restarted the instance. I was hoping to remove the initial file as it's not required and does not match the size+growth of the others. The option to 'remove' it is greyed out in the files tab of the GUI so I'm assuming that ALTER DATABASE [tempdb] REMOVE FILE [tempdev] will also fail.
Do I need to migrate any data in this particular .mdf before it can be dropped? Or would the simplest approach be to change the size of this file to match the others and drop tempdev3?
This is the output from sp_helpfile
Thanks
