I'm trying to free up some space in my Testing SQL Server. It has SQL Server 2005, 2008, 2008R2 and the compact or express edition. Since I only use lately the 2008R2 version, its not clear for me from the Program Files which of the older folders I should delete (if I'm doing this right?). I see folders named as (80, 90, 100, MSSQL.1,MSSQL.2, MSSQL.3, MSSQL.4, MSSQL10_50.SQL2008R2...)
I will keep the ones that has the 2008R2 obviously, but is there a better way to not accidently delete something that I'm not supposed to?
I'm using MS.Windows Server 2003 R2 Enterprise Edition. Thanks
