Windows has a disk partitioning system where C drive generally stores all the system files and program installation files. Those who have smaller storage capacity or the ones who play heavy games know that someday or the other, the paucity of space in C drive pops up. And the storage issue with C drive has become significantly worse after Microsoft started pushing Windows updates that are cached and stored in the C drive for recovery purposes. In such a scenario, you don’t have many options other than increasing the C Drive space. However, the process is not straightforward. That’s why we bring you an in-depth guide on how to extend C Drive Space on Windows 10. So without further delay, let’s begin.
Extend C Drive Space on Windows 10 Natively
Here, we will learn how to extend the storage of C Drive on our Windows 10 computer. We are using the native Windows tool — Disk Management — to increase the space of C Drive. As for your files and folders, be assured, no data will be lost during the process. But before we move ahead, let me give you a brief overview of how we are going to extend the C Drive storage.
I am assuming that you have made a back up of all your files from D Drive. Now, right-click on D Drive and click on “Delete Volume”. It will format the partition and make it an unallocated partition.
A pop-up window will open up. Keep clicking on “Next” and finally click on “Finish”.
Extend C Drive Space with AOMEI Partition Assistant
In the above section, we merged the whole D Drive with C Drive. However, if you want to add just 10 or 20 GB or whatever part of storage from D or any other drives then you can use AOMEI Partition Assistant (Download). It’s a third-party partition manager that comes with a broad range of features. Keep in mind, even this way, you need to back up all your files just to be on the safe side of things.
Further, if the native method didn’t work above then I would recommend you go through this method. Sometimes, the “Extend Volume” option for C Drive is greyed out in Disk Management. So in that case, you can use AOMEI Partition Assistant.
- Next, right-click on the newly-formed drive having a storage of 21GB (in my case) and select “Merge Partitions”. By the way, this partition is called the unallocated drive.
