I built my PC last year and followed some old advice that led me to create separate partitions for my OS on the C drive and everything else on the D partition. This setup has been giving me a lot of headaches, and I now want to combine both partitions into one to streamline my storage. Any advice on how to do this? Thanks!

Using third-party software like MiniTool Partition Wizard can make merging partitions easier. But again, reliable backup is crucial before you start resizing or merging anything!
You can merge your partitions using Windows Disk Management. Just make sure to back up your data first because deleting the D partition will wipe everything on it. Once you've backed up, delete the D partition and extend your C drive into the available space. But be cautious; some applications may still reference the D drive, so double-check where your files are located before proceeding!
If the programs expect to find files in D:, what happens if I delete it?
Merging partitions can be risky. What specific issues are you facing that make you think a single partition would be the solution to your problems?
The latest problem I'm having is with Steam; it says I need 16GB of free space to launch a game, but my C drive is full while my D drive has 700GB of free space. That's frustrating!
If you combine the partitions using Windows, typically, you'd need to reinstall Windows. I heard there used to be a software called Partition Magic for this, but it’s now a paid service. You could try EaseUS Partition Master for that now.

What would be your recommendation for backing up everything? Another drive, or some cloud service?
