How to partition a hard drive in Windows 11 without losing data?
Hi everyone,
There is too much free space on C drive and I want to split C drive into two partitions. I’m currently running Windows 11 and looking for a way to partition my hard drive in Windows 11 without losing data. I’ve done some basic research but I’m still unsure about the best approach to ensure everything remains intact.
Has anyone here successfully partitioned their hard drive without risking data loss? I’m particularly interested in using Windows’ built-in tools like Disk Management, but I’m open to other methods if they are reliable and easy to use. Here are some specifics:
- I want to shrink the main C: drive to create another partition for storing files.
- My data is not backed up, so I’m cautious about taking any risks
- Are there any precautions I should take before starting this process?
Thanks in advance for any advice or step-by-step guidance!

FabianPark Where is partition manager in Windows 11? By default, the Partition Manager is accessible through the Disk Management tool. Right-click the Start button (or press Windows + X) to open the power user menu. Select Disk Management from the list.
This will open the Disk Management window, where you can view and manage partitions, including creating, deleting, and resizing them. You can also assign drive letters, format partitions, and manage basic disk configurations.
P.S. If the stock partition manager does not work on Windows 11, it is advisable to try other alternative solutions instead as it only has some basic function for partitioning hard drive on Windows PC.
Using Command Prompt to partition a new hard drive in Windows 11 is a more technical way, but it works just as well. I've tried it myself and it works pretty well. Here are the steps:
- Open Command Prompt (Administrator mode).
- Type diskpart, then use list volume to find your C drive.
- Then type select volume X (X is the number of your C drive).
- Then use shrink desired=XXXX to shrink the space you want (XXXX is the number of MB you want to partition).
Finally, type create partition primary to create a new partition.
Although this method may seem a bit technical, it's not a big deal if you follow it step by step. However, it's recommended to back up important data before using it, just in case.
- Once you've created those partitions, it can be a hassle to resize or move them later on. If you find that your new partition is too small or you need more space on the C drive, you might be stuck. It's doable with some software, but it can get pretty technical and time-consuming. I had to take some extra steps once to reclaim space, and let's just say it wasn't as fun as I hoped.
Sometimes, after partitioning a hard drive in Windows 11, you might end up with a chunk of storage that's not being used effectively. Like, if you make a partition for files but never really fill it up, you've just carved out space that could've been part of your main drive. I've experienced this; I created a larger partition than I actually needed, not realizing I'd just have a bunch of unused space sitting there. It's actually pretty easy to partition a hard drive in Windows 11 using the built-in Disk Management tool. I've done this before, splitting the C drive into two partitions to store files. All you have to do is right-click "This PC", select Manage, and then click Disk Management. Find the C drive, right-click and select Compress Volume, enter the amount of space you want to compress, and all that's left is to create a new partition. Remember to leave enough space for the C drive so that the system won't have any problems. The process was pretty smooth, but I would back up my data before doing it, just to be safe!
Specific steps:
- Open Disk Management (right-click "This PC" -> Manage -> Disk Management)
- Right-click the C drive and select Compress Volume
- Enter the amount of space you want to compress and create a new partition
- Note: Make sure to leave enough space for the C drive to avoid system problems.

This method does sound simple, using the Disk Management tool to partition hard drive in Windows 11. But I'm a little curious, how do I determine how much space to leave when compressing the C drive? Is there a recommended minimum amount of free space to avoid system problems? Also, if there is an error or failure during the compression process, will it affect the existing data on the C drive?
