Change named instance file location after the instance was created!

Greetings -

I installed a named instance, and realized that I have made a mistake with the file paths (not specifying the data and log drives correctly). When the named instance was created, it created c:\program files\Microsoft SQL Server\MSSQL10_50.InstanceName. What I want is to have the data files go to F:\Data and logs to E:\log. How I change the file locations to be copied to these two folders instead of going to C:\program files? Do I have to remove and reinstall the instance name to correct the file locations of SQL?

Thanks,
