How to Shrink a Volume in Windows 10

On new laptops with preloaded Windows, you will mostly find single volume occupying full Hard Disk space. So, you may only have ‘C‘ drive (Windows drive) and no other volumes. However, you can shrink existing volume in Windows 10 and create a new volume using freed up space.

But remember, you can only shrink free space left in your disk drive otherwise, there may be a data loss. For example, if your C drive is of 500 GB with 300 GB used and 200 GB free space, you can shrink only up to 200 GB of your C drive space. And shrinking more than that will cause data loss.

One more important thing before we start. The data in HDD is not aligned systematically. The data get scattered in HDD disc over the time. So, we recommend you to run defragmentation first.
