My Sonar 2015 is installing as we speak. Some of the content installed to my C: drive whereas some of the content automatically installed to my H: drive, which is what I wanted. It's strange because I forgot the set the H: drive everything in the C3 options.
 
Is there a way to change the content's locations after installation? Do I have to move everything manually? I want to keep Sonar on my C: drive, but all the extras (samples and whatnot) can go on the other. I meant to set this option before I installed but was so excited that I forgot. lol

I'm pretty sure you can move the content anywhere you want. I just installed it to get the local help files and deleted the actual content folder. Nothing is complaining...

You should check in preferences and change the directories there. At least I think that would be the better option.
