Expand C Drive partition

Thanks Marcelo. I followed the first part of your instruction and reduced the E: partition by 20 GB, giving the following result:

Unfortunately the Extend volume option for C: is not available.

Sorry for the delay in answering, I was thinking about your case and I asked some friends of mine.

When the unallocated space is not directly behind the volume partition, which you need to extend, you cannot extend it. And the Extend Volume option will be grayed out. Therefore, your best option is to delete the partition right behind the volume, which you need to extend. That way you can extend it then.

But I believe that this option for you is not viable because you must have files on this other volume. One idea they had is to use a program to do it. The name of the program is EaseUS Partition Master

It's free I always use it with other problems on windows. I'll leave the link for it below:

Using this program the steps would be:

Step 1. Launch EaseUS Partition Master

Step 2. Add space to system drive C

1. Shrink partition and leave unallocated space to extend drive C.

Right-click on a partition next to the C: drive and select "Resize/Move".

Drag the end of the partition next to the C: drive and shrink it, leaving unallocated space next to the system's C: drive and click "OK".

2. Right-click on the C: system drive and select "Resize/Move".

To add space to the C: drive, drag the edge of the system partition into the unallocated space.

Step 3. Confirm to extend the system C drive

Click the "Perform operation" button, it will list pending operations and click "Apply" to execute the changes and extend the C drive.

Hello how are you?

I`m Marcelo de C., an independent Advisor. It is a pleasure to help you today.

In this disk management screen, right click on drive E:

Click decrease volume and enter the volume you want to decrease (this value is in MB).

Be careful not to decrease it with the next default value as it will decrease the entire partition.

After decreasing the need it will open an unallocated unit in black.

Right click on the C: drive and place the volume extend.

Once this is done, the volume will extend to the unallocated area of ​​the system.

I hope the information above helps. Please let me know how it goes.

Have a nice day and stay safe.

Marcelo de C.

This is one reason why I keep my important data on a separate drive. Or at least have a full backup of data on another drive. Then you can always delete the problem data partition. When you fool with moving data something might go wrong. If moving works then you're OK.

Thanks for your patience Marcelo!

When trying to run the command extend size=n disk=0, I keep seeing the error message

"Virtual Disk Service Error: There is not enough usable space for this operation."

I started with size=20000, then 19530 (the free space is shown in Computer Management as 19.53 GB), then 10000, then 5000. I understand that this is the amount of space to increase the volume by, rather than the total size after extending.
