Splitting TempDB into multiple data files.

Question

To avoid contention we have to split tempdb into multiple data files. But as for case suppose, there is 20 GB total space is on the drive containing 1 tempdb data file of 15 GB. And I have to create 3 more tempdb data files, and as recommendation all files
should be of same size.Then how to handle this situation and configure all data files with same size?

But as for case suppose, there is 20 GB total space is on the drive containing 1 tempdb data file of 15 GB. And I have to create 3 more tempdb data files, and as recommendation all files should be of same size.Then how to handle this situation and configure
all data files with same size?
So your goal is to have 4 tempdb files, each 5GB?  Below is a sample script to accomplish the task within the 20GB space constraint.
--reduce size of existing file to 5GB
ALTER DATABASE tempdb
MODIFY FILE (NAME='tempdev', Size=5GB);
DBCC SHRINKFILE('tempdev',5120);
--add 3 new 5GB files
ALTER DATABASE tempdb
ADD FILE (NAME='tempdev2', FILENAME='D:\SqlDataFiles\tempdb2.ndf', Size=5GB);
ALTER DATABASE tempdb
ADD FILE (NAME='tempdev3', FILENAME='D:\SqlDataFiles\tempdb3.ndf', Size=5GB);
ALTER DATABASE tempdb
ADD FILE (NAME='tempdev4', FILENAME='D:\SqlDataFiles\tempdb4.ndf', Size=5GB);
