How to Extend C Drive Space on Windows 10

The C drive typically houses all of the system files and software installation files according to the disc partitioning mechanism used by Windows. People with smaller storage capacities or those who play demanding games are aware that the C drive will eventually run out of space. And since Microsoft started pushing Windows updates that are cached and saved in the C drive for recovery purposes, the storage problem with C drive has significantly gotten worse. There aren’t many solutions available to you in this situation outside from expanding the C Drive. The procedure is not simple, though. Because of this, we are providing you with a thorough explanation on how to increase C Drive Space on Windows 10. So without further ado, let’s get started.

  • Extend C Drive Space on Windows 10 Natively

Here, we’ll cover how to increase C Drive’s storage on a Windows 10 PC. Disk Management, a built-in feature of Windows, is being used to expand the size of C Drive. You may rest confident that no data will be lost in the process when it comes to your files and folders. But before we continue, allow me to give you a quick rundown of how we plan to increase the storage on C Drive.

First of all, the nearest drive, D, must be empty and unallocated before you may increase the volume of C Drive. E, F, or the following drive cannot be used to increase the storage on the C Drive. Therefore, you must either transfer the files on your D drive to other drives, such as E or F, and so forth. In the event that none of the drives have any free space, back up your D Drive files to an external hard drive. Simply put, back up your D drive’s data and leave it empty because we’ll be merging it with C drive.

1. Click the Disk Management option in the context menu of the Windows Start Menu.

2. I’m presuming you’ve created a backup of every file on D Drive. Right-click on D Drive and select Delete Volume to proceed. The partition will be formatted and turned into an unallocated partition.

3. Next, choose Extend Volume by right-clicking on the C disc partition.

Note:You may need to use a third-party tool if the Extend Volume option is greyed out. In the part after this, we have listed every instruction. But first, right-click the empty partition and select New Simple Volume from the menu. Continue clicking Next after that to create a new drive. This division can be used in the next section.

4. An alert window will appear.

Continue selecting Next until you reach Finish.

  • Extend C Drive Space with AOMEI Partition Assistant

5. Your C Drive will finally be combined, instantly increasing storage space. So, this is how Windows 10 users can increase the size of the C drive.

We combined the entire D Drive with the C Drive in the section above. However, you can utilise AOMEI Partition Assistant if you only want to add 10 or 20 GB or any other amount of storage from drive D or any other drive (Download). It is an external partition manager with a wide range of capabilities. Remember that even using this method, you should backup all of your files to be safe.

Additionally, if the native technique above didn’t work for you, I would advise using this way. Disk Management occasionally displays the C Drive’s Extend Volume option as greyed out. You can therefore use AOMEI Partition Assistant in that situation.

1.Right-click any drive with free space, then choose Resize/Move Partition. If you came from the section above, select the newly created partition that you made using a basic volume.

2. After selecting how much RAM you wish to keep on the existing drive using the slider, click the Ok button. As an illustration, I kept about 800GB out of 821GB, which implies I am removing 21GB from the drive already in use. This 21GB file and C Drive should be combined. You get to pick the storage area you want.

3. Next, pick Merge Partitions from the context menu of the newly created disc, which in my instance has a storage capacity of 21GB. By the way, the unallocated disc is the name of this partition.

4. Click the Ok button after choosing the C: drive and the unallocated drive from the list.

5. To complete the changes, click the Proceed button after clicking the Apply button in the top-left corner. Remember that the entire process could take up to 20 or 30 minutes. The PC will restart many times. If you do make a mistake, don’t stress. You can boot back into your computer by simply restarting it.
