Windows 10: Windows 10: Disk C is full and Disk D is almost empty, however I cannot use available space...

I am running short on diskspace on C:\ and I decided to move some data about 30Gb to D:\ in order to free up space.

To my surprise, although it seems that there are 800Gb of free space in D:\, I receive the following message



Please see below how the disk management looks like. How can I assign more space to C:\ ?

The extend option is not available for the C:\ drive

c drive and d drive disk particitions space

Any chance you could use the snipping tool to take a picture of your Disk Management window and attach?

Depending if there is a Recovery partition after the C partition, you may need to remove the D partition and extend C then recreate D in the space available.

If you are restricted by a recovery partition you will need to use a third party disk management software.

 

Disk space.

Could be the Windows Update Stores files, .old files, shadow copies, etc.

Try running Windows disk clean up with the "Clean up System Files" option.

Delete files using Disk Cleanup <-- Be sure to check out the section at the bottom "To clean up all files on the computer".
