Merge partitions in Windows 7
Sometimes you need to merge disk partitions together, for example: there are too many drives causing it difficult to locate the partition and files, so you may consider combining some drives. Another reason why some people want to merge partitions in Windows 7 is because C drive getting full. By merging drive D to C, there will be more free space in C drive again.
If you want to combine two data volumes, either Windows 7 native Disk Management or 3rd-party partitioning software can help you. But if you want to combine C and D drive, it is not a good idea. In this article, I’ll show you how to merge partitions on Windows 7 (32 & 64 bit) and extend C drive by resizing partition instead of merging.
Combine partitions with Disk Management
Windows 7 Disk Management has no “Merge Volumes” feature, but you can accomplish with Extend Volume indirectly. For example if you want to merge drive D and E, follow the steps:
- Back up or transfer all files in drive E to other place.
- Press and on keyboard to open Run, type diskmgmt.msc and press Enter to open Disk Management.
- Right click drive E and select Delete Volume.
- Right click drive D and select Extend Volume, simply click Next to finish.
However, there is a restriction that cause you cannot merge partitions with Extend Volume. In my Windows 7 laptop, I deleted drive E, but Extend Volume doesn’t work for D.
This is because: Free space deleted from Logical partition cannot be merged into Primary partition, Unallocated space deleted from Primary partition cannot be combined to Logical partition.
Another restriction: if drive D is formatted as FAT32, you cannot combine it with other drive even if this drive is Primary, because Extend Volume does not support FAT32 partition.
If you can’t merge partitions because of these restrictions, you have to use professional disk partition software.
Merge partitions with software
With NIUBI Partition Editor, all adjacent drives can be merged, no matter they are Primary or Logical partition, NTFS or FAT32 partition. In addition, you can combine partitions on Windows 7 by only several clicks.Download NIUBI Partition Editor, you’ll see all disk partitions on the right and all available operations on the left. I’ll show you how to merge hard drive D and E.
Right click drive D or E and select “Merge Volume“.
In the pop-up window, click the check-box of both drive D and E, and then click the drop-down box to select destination drive.
If you select drive D in the drop-down box, drive E will be merged into D. As you see, there is a pending operation “Merge volume E to D” created on bottom left, click Apply on top left to execute.
Open drive D after it complete, a new folder named as “E to D(with date and time)” is created. All files in original drive E are moved to this folder automatically.
Merge partition C and D
If you want to combine drive C and D, the steps are the same with above except one selection. When merging 2 drives, all files of a drive will be moved to the other one, but this drive will be deleted. C drive is where Operating System located, of course it cannot be deleted, so when merging drive C and D, D is disabled as destination.
Resize partition instead of merging
Different with other data volumes, programs are installed in drive D, so it is not a good idea to extend C drive by merging D. Though all files will be transferred to C, all shortcuts of these program become invalid.
With NIUBI Partition Editor, you can shrink drive D to get some free space and then add into C drive, so partition D won’t be lost and everything keeps the same. Watch the video how to do this:
To merge partitions on Windows 7, the native Disk Management can help you in some way, but you cannot merge all drives because of the restrictions. NIUBI Partition Editor is much easier without such limitations. If you want to extend C drive, you’d better shrinking D or other drives, so no partition will be lost and everything keeps the same after resizing.
