These files are essential to run an application, and things stop working if you directly move these folders somewhere else. However, the size of these apps partially increases after a long time, slowing down the system. 

We recommend that you use EaseUS Partition Master to migrate large programs easily. The tool provides an AppMove feature that helps you easily migrate C drive programs to D drive in one click to free up space.

FAQs About How to Use D Drive in Windows 10 

You might have several questions about how to use your D drive in Windows 10 if you are looking to manage your storage. This FAQs section will address common queries related to this topic.

1. Can I use D drive instead of C drive? 

Unfortunately, using the D drive instead of the C drive is not feasible. This restriction results from the fact that the Windows operating system, which contains crucial system files, is installed by default on the C drive. While you can use the spare space on the D drive to store important information, we do not advise utilizing it as your primary drive instead of the C drive.

2. How to create a D drive in Windows 10? 

To create a D drive in Windows 10, create a new partition and name it a D drive. To do so, go to the "Search bar" and type "Disk Management." Click the right mouse button on any free space and choose "New Simple Volume." Follow on-screen instructions to create a new partition and assign it a drive letter as D.

3. Why is the D drive not showing up in Windows? 

If Windows does not recognize the D disk, it could be due to the following reasons:

  • The D drive has no assigned drive letter.
