After using a computer with Windows 10 installed for a long time, you may encounter Low Disk Space warning on C drive. It is really a troublesome issue especially for the user whose work depends on computer such as game testers, editors, designers. To fix it, apart from freeing up space on C drive via moving apps to another drive, running disk cleanup, and so on, you can also try extending C drive.
Usually, your C drive is the partition that contains OS information. Here we offer you 3 effective and simple ways to increase C drive space in Windows 11, 10, 8, 7. You can choose one according to your demand.
If there is an adjacent unallocated space behind C drive, you can extend it in Windows 10/11 Disk Management. Here are detailed steps:
Step 1. Press Windows + R at the same time to open Run dialogue.
Step 2. Input diskmgmt.msc and hit Enter to open Disk Management.
Step 3. Right-click C drive and choose "Extend Volume".
Step 4. Follow the prompts that will appear to complete this operation.
Note: If the unallocated space is not adjacent to the C drive on its right side, the "Extend Volume" will grey out and cannot be clickable.
When there is a contiguous adjacent unallocated space behind system partition, you can also choose to extend it in Diskpart utility.
Step 1. Open Run dialogue, input diskpart and click OK.
Step 2. Run commands as follows:
▶ list disk
▶ select disk n: n refers to the number of the disk that holds C drive.
▶ list partition
▶ select partition m: m is the number of C drive.
▶ extend size= x: x is the size in MB you want to add to the system partition.
Note: Same as the Disk Management, the DiskPart can only extend C drive when there is an adjacent unallocated space on its right side.
From the previous content, we can know that both the Disk Management and DiskPart have the same restriction: only extend a volume when it is followed by a contiguous unallocated space. Besides, they can extend NTFS partition only. If the C drive is of FAT32 file system, they cannot help you, either.
In such cases, you had better employ third-party partition manager software, such as AOMEI Partition Assistant Standard. This freeware can extend C drive more flexibly. For example, it can directly merge unallocated space, no matter where it locates on the hard disk, into the C drive by 3 steps. Besides, you can move partition to make unallocated space adjacent to the to-be-extended partition and then extend it successfully. You can free download it to see how to extend C drive in Windows 10.
