2. Extend C Drive Space in Disk Management by Deleting Partition
Disk Management comes with Windows and has many functions to manage disks, including extend volume, shrink volume, format partition, delete partition, etc.. You can use the “Extend Volume” option for increasing C drive space if you don’t want to use the third-party EaseUS Partition Master to extend C drive.
Yet, there is a condition when extending C drive via Disk Management; that is, there needs to be some unallocated space very behind the C drive. Otherwise, the extend volume will be greyed out.
If there is no unallocated space, how to increase the space in C drive? We should first create unallocated space by deleting partitions and make sure it locates right behind C drive. Then, extend C drive with the unallocated space. Do it by following the guides below.
Next, we will show an example of how to increase C drive space by removing D drive, which is very behind C.
Step 1. Open Disk Management, right-click partition D, and choose “Delete Volume”. When the process finishes, we can see there is unallocated space and locates right behind C drive.
Step 2.Now, right-click on C drive and select “Extend Volume”. Extend Volume Wizard will pop up. Follow the on-screen guide to complete increasing C drive.
