Fix 'there is not enough space available on the disk to complete this operation'

Not enough space error message in Windows Disk Management:

Error 1 - "Not enough memory available to complete this operation. Quit one or more applications to increase available memory, and then try again."

Error 2 - "There is not enough space available on the disk(s) to complete this operation."

As we use the Disk Management to create, extend, or shrink partition, you may encounter such "no enough space" error because the tool has limitations. When your computer says it's running low disk space to execute a certain task with the below error messages, don't be fooled. Why does such an error message pop up on your PC? There are two typical reasons.

One. Due to the limitation of the extended partition and Disk Management tool itself, you cannot create a new partition on free space. Instead, you must delete the free space and turn it into unallocated space.

Two. It's only because you're not utilizing the memory right. Many Windows users prefer to install applications and store data files to the system drive, soon the drive will be filling up. And then, such an error generates.

However, if you try to move unused space from drive D:, E: or F: to drive C: with the Disk Management program, you'll find that extend volume is grayed out if there's no unallocated space right behind your target disk (which has not enough space). So, we've collected the following solutions to help you resolve this error happened on your computer disk.

Solution 1 - Extend low-memory partition to fix "not enough space" 

When the Windows Disk Management program sends "there is not enough space (or free memory)to complete this operation" error, it seems that you'll then have no choice but to close the window.
