Windows 10: Extending the C Drive Partition

I have 368.10GB free on the installed M.2 drive however I am unable to extend the "Boot Drive C:" partition within it. I have tried multiple things but I would like to avoid reinstalling windows if possible. The "Extend Partition" option is always greyed out. Please advise.

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!

 

How to extend C partition

Hi Kevin,

Thank you for posting your query on Microsoft Community.

I would suggest you try the following steps and see if it helps.

1. Right-click on the partition (in your case, Data) and select
Delete Volume.

2. When the prompt appears click Yes.

3. The partition will now display as Unallocated.

4. Now, right-click on C: Drive and select Extend Volume.

5. Click on Next. If you wish to extend all the unallocated partition to C: drive, then click
Next otherwise next to select the amount of space in MB
text box type in the space (in MB) to merge with C: drive.

6. Click on Finish.

Note: In disk management, D: drive must be next to the C: drive on the right-side only then you can extend C: drive.

Hope this helps. Please respond if you have further related queries.

Regards,

 

Windows 7 Drive C extend partition

Hi,

I have a problem extending my drive c partition, here's the scenario:

Basically, I have 2 partition, the drive C and drive D. Since I am no longer using the drive D i want to delete the partition and add it to drive C.

Heres what I've done,

I navigate to disk partition manager and delete the Drive D partition after that i right click the Drive C partition to extend its storage but the extend button is disabled.

Next, I use my bootable windows 7 installer and choose the advance method installation, there, i was able to extend the partition, but, i want to know if extending the Drive partition will remove my drive c data ? I dont want that to happen. . I want just
to extend its storage thats it. So that i can be only using Drive C.

Thanks. .
