July 2,2020
Many people allocated less space to the C drive due to inexperience, resulting in troubles in computer using for out of space on C drive. Here, I will introduce to you how to add space to C drive from D drive in Windows 10 to solve the issue of insufficient C drive space.
BTW, to avoid the situation of running out of space, I suggest allocating more space to the C drive. The recommended size of C drive is about 150G.

Extend C drive space from D drive
Step 1: Manually copy the data of the D drive to another partition (select all -> right-click -> copy), or apply the software CloneGo to back up the data of D drive. You can follow the procedures shown on the picture below to back up data.
Download: CloneGo
Note: Someone may say you can release the D disk space through Shrink Volume. But actually, the space released from D drive by shrinking is not close to the C drive and cannot be used directly. Instead, it may lead to a mess. And Shrink Volume operation won't be faster for data move is also needed.
Step 2: Open Disk Management: Right click on My PC -> Manage -> Disk Management -> right-click D drive ->Delete Volume.
Step 3: Right-click C drive, select Extend Volume and then enter the space size you want to add to C drive.
Step 4: Right-click on unallocated space -> select New Simple Volume, and the New Simple Volume Wizard window will pop up. Select Next in the popup window, then set the new volume size, and the default is to include all of unallocated space to it.
The picture below shows the drive letter or path you can assign for the new volume.
Step 5: Lastly, copy the original data back to D drive. Or utilize the app CloneGo, which is mentioned above, to restore your backup data on another drive before. All operations are completed!
Tip: If any step cannot be operated, please restart the computer and operate again.
As a result, the C drive is expanded from the space formerly occupied by D drive, and the D drive space is reduced. Besides, you can also employ the same method to extend the C drive from other volumes which still have much free space, like E drive, F drive, or G drive.
