Storage management used to feel like one of those techy things best left untouched, until I ran out of space right before a deadline. That was my crash course in Windows 10 Disk Management. It turns out there’s a built-in tool that lets you do everything from creating partitions to cleaning up cluttered drives, and no extra software is needed. Once I got the hang of it, I started using it regularly to stay organized and make the most of my space. In this guide, I’ll walk you through how to manage your Windows 10 disk like I did, from opening the tool to resizing or deleting partitions. If I could learn it, you definitely can too.
How to Open Disk Management in Windows 10
Before we start moving things around, we need to know how to open Disk Management in Windows 10. This is the control center for your storage, and luckily, getting there is pretty simple. Here's how you can get there in multiple ways.
Step 1: Hover down to the bottom-left corner of your screen and click the Start button (yep, the one with the Windows logo). From the menu that appears, either type "Disk Management"
Step 2: Or just press Windows + X and choose Disk Management from the list. It’s a shortcut I now use all the time.
Step 3: Alternatively, press Windows + R to bring up the Run dialog, type diskmgmt.msc, and hit Enter. This method gets you straight in.
Just a heads-up, you’ll need admin rights for changes. When I first tried this, I had to switch accounts just to proceed. If Disk Management is not working, double-check your admin rights or try restarting the tool, as these steps might sometimes require elevated privileges.
How to Create a New Partition in Windows 10 Disk
Now that you’re in, let’s say you want to create a new space to separate personal files from work files. That’s where a partition comes in. The built-in tool makes it pretty straightforward to create a Windows 10 partition without needing any third-party software. Let me show you how to do it step by step.
Step 1: Open up Disk Management using one of the methods above.
Step 2: If you see a gray area labeled Unallocated, right-click on it and choose New Simple Volume.
Step 3: A wizard will pop up, just follow along. You’ll set the size, assign a drive letter (like D: or E:), and format it (usually NTFS is fine).
No unallocated space? Right-click on an existing partition, choose Shrink Volume, and create room first. I once did this to set up a dedicated backup section, it’s cleaner than dumping files everywhere.
How to Extend an Existing Partition in Windows 10 Disk
Maybe your main drive is running out of space, and you want to give it a little more breathing room.
Step 1: Open Disk Management again.
Step 2: Find the partition that’s feeling cramped, right-click on it, and select Extend Volume.
Step 3: Again, the wizard will show up, just follow the steps here, you can either go with the maximum amount of space or set your own space, just click next, and your setup should be done.
Ensure that unallocated space is adjacent to the partition you want to extend. The tool won’t work if there’s another partition in between. This tripped me up early on. Also, don’t convert to dynamic disk unless you fully understand the limitations it brings, as this could affect how you manage your partitions going forward.
How to Delete a Partition in Windows 10 Disk
Let’s say you created a test volume and no longer need it, or maybe you're cleaning up clutter.
Step 1: Launch Disk Management and take a close look at all your volumes.
Step 2: Right-click on the partition you want to get rid of and click Delete Volume.
Step 3: Windows will ask for confirmation. Say yes only if you’ve backed up the data.
Deleting a partition will erase all data on it. Ensure you back up important files before proceeding. I almost accidentally ended up wiping out everything I had before; luckily, my low battery saved me. Be extremely careful if you’re thinking of deleting the recovery partition, as these can be important for system restoration.
Manage Windows 10 Disk by WPS OFFICE
One thing I’ve learned while working with Windows 10 Disk Management is that organization doesn’t end with the partitions themselves, it continues with how you document and plan your storage strategy. That’s where WPS Office comes in. It’s not just a free alternative to Microsoft Office; it’s a surprisingly powerful companion when you’re managing your system.
I often use WPS Writer to jot down changes I’ve made to disk structures or keep notes on backup strategies. WPS Spreadsheets is perfect for tracking partition sizes, drive letters, and space allocations, especially when I’m handling multiple drives. And when I need to explain a disk layout to someone else, say, a client or a teammate, I use WPS Presentation to lay it all out visually.
Since WPS supports all the common file formats and has a clean, fast interface, it makes the process of managing and documenting disk setups feel seamless.
One of the things that really stands out about WPS Office compared to Microsoft Office is how well it integrates AI features. Whether you’re working on a presentation or need to translate a document, WPS gets the job done quickly. Its AI tools are great for helping with things like formatting, editing, and even generating content, which can save you time and make your workflow a lot smoother. It really helps cut down on the repetitive stuff!
FAQs
Q1: Can I merge two partitions using Disk Management?
No, Disk Management does not support merging partitions directly. You would need to delete one partition to create unallocated space and then extend the other partition into that space.
Q2: Is it possible to change a drive letter in Disk Management?
Yes, right-click on the partition, select Change Drive Letter and Paths, and follow the prompts to assign a new letter.
