How to extend C partition

Hi Kevin,

Thank you for the information provided.

Please to inform you that you need to have an “unallocated disk space” to the right of the Partition\Volume you wish to extend on the same drive. Only when “unallocated disk space” is available “extend” option is highlighted.

I suggest you to try these steps and check if they helps.

Step1: Press Windows + R and Diskmgmt.msc and try the following

a. Right click the basic volume want to extend.

b. Click extend volume.

c. Follow the instruction on the screen.

Step2: Open a command prompt and type diskpart.

At the DISKPART prompt, type list volume. Make note of the basic volume you want to extend.

At the DISKPART prompt, type select volume <volumenumber>. This selects the basic volume volumenumber that you want to extend into contiguous, empty space on the same disk.

At the DISKPART prompt, type extend [size=<size>]. This extends the selected volume by size megabytes (MB).

Hope this helps. If the issue remains unresolved, please get back to us and we would be happy to help.

 

Extend C drive Size

Your Image does not show a D partition. It does show an F partition which if reduced in size would enable you to increase the size of the C partition.



These are the steps needed to enable you to increase the size of your C partition:

• 
  Reduce F by 20 gb placing the unallocated space before F.
  
• 
  Increase the Recovery partition by 20 gb taking up unallocated space created by Step 1.
  
• 
  Reduce the Recovery partition by 20 gb placing the unallocated space before the Recovery partition.
  
• 
  Increase the C partition by 20 gb to take in the unallocated space before the Recovery partition.
  

You can use Easeus Partition Manager (freeware) to carry out these tasks. The files in each partition are automatically moved when you carry out each step detailed above.

extend c drive storage space

Hi, I'm , an Independent Advisor.

Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

- Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

- The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

#1. Increase C Drive Space with Adjacent Unallocated Space

Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

Step 3. Set and add more space to your system C drive and click "Next" to continue.

Step 4. Click "Finish" to complete the process.

Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

Hope this helps. Let me know if I can help you further!
