Hi, Other than doing the fdisk and deleting the present C: drive and then fdisking again and creatig a new C partion using all the space and reinstalling everything, you will have to obtain a 3rd party software, such as Partion Magic, to change the size of the partition. I do not believe Microsoft utilities included with thier OS will allow you to do it and keep your files and OS safe. God Bless America!
