now what you want to do is shrink your c partition to about 70GB and create a new partition using the rest of the space, then copy all your personal data files onto it. 
just joking (sort of.) and glad you sorted it to your satisfaction. 
the reason i say sort of joking is because some people think it's safer to have your data files on a separate partition to your operating system files.
personally i don't think so because if your hard drive fails then it doesn't matter where your personal files are located on it, you'll still be sol (might need to look sol up on google urban dictionary. not for kids hears/eyes anyway.
) if you haven't backed them up somewhere else.
so your main objective when running/using a pc is to always keep good backups (not on the same hard drive.) of all/any files you really don't want to lose.
