Rename in Windows Explorer

I use the rename function quite often with in Windows Explorer and has recently disapperared. The only option that shows up is to do the Pack and Go. I have lost the ability to Rename, Replace, and Move with in Windows Explorer. Is there an option some where that I accidently unchecked? I know I can do this through Solidworks explorer, just been used to using the features through Windows Explorer. Any help would be greatly appreciated.

Thanks in advance.
