I've been dealing with a frustrating issue where my C drive is only 118 GB and it's running low on space. I initially created a D drive but I couldn't move any storage from C to D, like transferring the Notion app. I decided to extend my C drive instead, but I messed up by shrinking the D drive, which is now labeled as 'New Volume E' and has 500 GB. The problem is, when I check my disk management, the C and D drives aren't aligned, and I can't seem to extend the E volume back to D. I'm looking for help on how to restore the E volume to D and then shift some space to the C drive. I've attached a screenshot of my disk management for clarity.

Also, depending on your setup, sometimes the best option is to clone your drives entirely if you can access the data. But it does take some extra steps and software, just a heads up!
You know, I think you should really consider using your 1TB drive as the main one. Having just 118GB for your C drive is pretty cramped. I used to have a 256GB and it barely worked for me unless I moved a bunch of stuff to an external USB drive. It could save you a lot of hassle!
If there’s absolutely nothing stored on the New Volume E, you can delete that volume by right-clicking it and then right-click on D to extend its volume. Just a heads up, extending C directly might require a bit more work since it can’t be done unless you have the right setup. You might need some special software for anything beyond that.
If Windows is giving you trouble with shrinking and extending your partitions, consider trying out AOMEI Partition Assistant or EaseUS Partition Master. They’ve worked for me in the past to fix partition issues, especially when I dealt with external HDDs that had multiple partitions.

I’m not sure how to transfer everything from C to D, though. Even new apps still default to C for installation. I attempted to move Notion, but it still says it’s using C storage.
