Why my C drive is full while my D drive is empty? The C drive is full for various reasons, including too much software installation and improper partition size allocation. Since the operating system is installed on the C drive, insufficient space on the C drive will lag behind the computer's performance. Luckily, I will offer two practical solutions to help you escape this.

Solution 1: Merge C and D Drive

The best and most straightforward solution to "C drive is full, but D drive is still empty Windows 10" is to merge C and D drives. If you want to make this process simple and quick, you'd better turn to a powerful partition manager software for help to avoid any file loss or system errors. I highly recommendob欧宝app , which provides a tool called Partition Manager that can help you efficiently merge two drives.

Install EaseUS Partition Master and learn the simple steps as follows:

Step 1.Run EaseUS Partition Master and right-click on the C drive to select "Merge."

Step 2.Select a neighbor drive to merge, and click "OK" to continue.

Step 3.Click the "Execute Task" and "Apply" to confirm the merge process.

Solution 2: Extend C Drive with Unallocated Space

The second way is to use or create unallocated space for the C drive, which EaseUS Partition Master can lend you a hand. If you already have plenty of unallocated space on your disk. Be aware that you can only adjust the unallocated space when it is adjacent to and behind the C drive. If your D drive is empty, you can delete it to create unallocated space for the C drive. Here is how to do it:

Step 1.Launch EaseUS Partition Master and enter "Partition Manager."

Step 2.Right-click on D drive and choose "Delete."

Step 3.Click "Yes" > "Execute xx Task" > "Apply" to confirm the deletion.

Step 4.Right-click C dive, choose "Resize," and drag the right end of C drive to extend space.

Step 5.Click "Yes" > "Execute xx Task" > "Apply" to confirm the extension.

If your C drive is full and already received a low disk warning, try the "Adjust with 1-Click" of EaseUS Partition Master following the guide below:
