Kindly Remind: to avoid confusion, we would like to explain that the C drive and D drive in this post mean the C: partition and D: Partition respectively.
With more and more data stored to C drive of Windows 7, now this partition is nearly out of space. However, there are lots of free space on D drive, so I want to know whether it is possible to merge C with D so as to enlarge system partition of Windows 7.
Definitely, users are able to merge partitions, and there are 2 methods available. One is to use the Windows built-in Disk Management tool, and the other is to ask a third-party partition manager for help.
Next, we will introduce these 2 methods to merge C drive and D drive in Windows 7 in detail, and users can choose the appropriate one in accordance with actual demands.
Merge C and D Drive in Disk Management - Data Loss
If users want to combine C and D via Disk Management, they need to back up all important data on D drive in advance, because this partition will be deleted. Naturally, all data saved in this drive will be lost. To back up data in a fast way, view the help tutorial Copy Partition to get instructions.
Then, let's see how to merge partitions in Disk Management.
Step 1. Press Win+R to call out the Run box, input diskmgmt.msc and hit the Enter key to load Windows Disk Management. (Another approach: right-click the Computer icon on the desktop, choose Manage and then Disk Management.)
Step 2. Right-click partition D and then choose Delete Volume button to release unallocated space.
Step 3. Right-click partition C to choose Extend Volume button. Then, extend volume C by following Extend Volume Wizard.

Well, is it possible to merge partitions without losing any data? Of course, with the help of third-party partition manager, it is easier to merge C and D drive in Windows 7.

Then, how to combine partitions? Let’s see detailed steps.
Step 1. Users need to launch MiniTool Partition Wizard to get its main interface.
Step 2. Now follow these two guides to create a bootable media and then boot your computer from this media.
