How Can I Remove All Windows Files Without Formatting? Help

I have a WD 1TB Black SSD, and I want to delete and merge the C: and D: partitions on Windows 7. I would like to know what other places besides the C partition hold the system files and if there is anything else I need to wipe out. Thanks!

If you are worried that deleting C and D partitions won't get rid of all your system files, you can also use the tools that come with Windows or professional disk management tools to view all hidden partitions, including user-hidden, third-party program hidden, and system hidden partitions. EaseUS Partition Master is a safe and easy-to-use tool to view all the hidden partitions.
