OS (C Drive - Extending the Volume

I've recently purchased a new laptop and came across a problem regarding the storage volume. It seems there's an arbitrary partition where C: drive has 100GB allocated and the remaining 900GB+ is unallocated. When I tried to extend the volume of C: to include
the 900GB, the option to extend the volume was grayed out and unusable.

Unfortunately, I just don't know enough to figure out why all that space is unallocated and why I can't extend the volume of the C: drive. Searching for the answer yielded a lot of suggestions for third-party software, but I'd like to avoid that solution
if possible. Are there any other options?

 

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!
