Why Split System Partition in Windows 7/8/10?

A user wrote his problem on the forum like this: my new laptop hard drive is 750GB and has only one partition (the C drive). All the available space is 676GB after my Windows installed. I intended to create a 120GB C partition in Disk Management with shrink volume, but it only creates a 339GB C drive at most. I just want to make a 120GB C drive and the rest of it (approximate 510GB) as the new partition for data storage. What should I do while the shrink option does not work, is there any tool to do this? Thanks a lot.
