How to Merge C and D Drives in Windows 8 with Ease

  • Question: there are 5 partitions in total on my old 500GB hard disk. Now drive C (system partition) is full though it was allocated with 80GB space while partition D is filled with free space. Therefore, I want to combine them. Who can tell me how to merge C and D drives in Windows 8 with ease?

    Answer: there are several ways to combine 2 partitions, and here we just introduce 2 of them. One is using Windows 8 built-in disk management tool, and the other is using third party partition manager.

    Though Windows 8 built-in disk management tool does not provide a function to combine 2 partitions directly, users can get the same effect by taking the following operations. Firstly, backup all important data on drive D to other partitions or external device. Then, open disk management by performing these operations: right click "Computer" icon on traditional desktop, choose "Manage", and select the item "Disk Management" in the left. Next, right click drive D and choose "Delete Volume" from the shortcut menu. Then, click "Yes" to start deleting. After successful deletion, partition D will be unallocated. At this time, right click drive C, choose "Extend Volume", and perform the remaining operations according to given wizards. Note: "Extend Volume" may be grayed out under some situations. At last, move the backup to drive C.
