Warning! C drive becomes red
During the usage of a computer, applications keep being installed into Windows system. One day, you may get mad at your computer because you have to wait for extra time when you try to launch an application or close it. It is absolutely annoying! And when you open "Computer", you'll find that C drive becomes red.
It is a warning that you are running out of disk space on C drive. You are supposed to delete old and unnecessary files, or move programs from C drive to other drive to make more free space. However, it proves useless when the problem comes again after a short period of time. Now you must be searching for a more effective way—increasing memory of C drive. If you don't know how to increase disk space in C drive safely, move on to the next part.
How to increase memory of C drive effortlessly in Windows 11, 10, 8, and 7
To optimize computer performance by increasing memory of C drive, there are three effective methods at hand.
▶ Method 1. Increase memory of C drive using Disk Management
As Disk Management is familiar to most computer users, what comes to you first is how to extend C drive using Disk Management. Follow the steps below:
1. Right-click the "Computer" icon on the desktop and hit the "Manage" option.
2. Click on "Disk Management" to open Windows Disk Management.
3. Select C drive, right-click and hit "Extend Volume".
4. Set the amount of space to be extended to C drive following Extend Volume Wizard.
Tip: The "Extend Volume" option can be greyed out if there is no contiguous unallocated space on the right side of C drive. On that occasion, if there are other partitions on the same disk, you can choose to delete the adjacent partition to create unallocated space, but you must make sure your crucial data have been backed up before that. The process might be time-consuming and error-prone.
▶ Method 2. Increase memory of C drive with Diskpart
Some people prefer to increase C drive space with Diskpart. Then, do the following steps:
1. Press Windows Key + R to open the Run dialogue. Type diskpart and click "OK".
2. Type list volume and press Enter.
3. Type select volume # (ex: Volume 1) to select C drive that you want to extend and press Enter.
4. Type extend size=# (ex: size=2048) to extend C drive by size in megabytes (MB) and press Enter.
5. Type exit and press Enter to exit Diskpart.
Tips:
● You may fail to extend C drive if there is no contiguous unallocated space on the disk.
● If you do not specify a size, C drive will be extended to take up all the contiguous unallocated space.
▶ Method 4. Increase memory of C drive via a handy software
Now you see the limitation of extending C drive with Disk Management and Diskpart. Here comes a handy partition manager— Qiling Disk Master Professional. It helps you increase memory of C drive as long as there is unallocated space on the same disk, whether it's right behind C drive or not. It also applies to other Windows operating systems, like Windows 11/10/8/Vista/XP, etc.
Step 1. Launch Qiling Disk Master. Right click C drive, select "Move/resize Partitions".
Step 2. Find unallocated space, and drag to it.
Step 3. Confirm "Proceed" to execute the operation.
Tip: You can see clearly from Step 1 that the unallocated space lies behind D drive instead of C drive. By "Merge Partitions" option, the unallocated space will be moved and added to C drive automatically.
Summary
If you find your computer works slower and slower, try to increase memory of C drive via three methods mentioned above. However, Qiling Disk Master is a powerful partition manager with more practical features. It can also help you move partitions, allocate free space from one partition to another and so on.
