May 11, 2016

It’s not complicate to merge or combine partitions for Windows 7 or other systems by using AOMEI Partition Assistant, with few clicks and easy operation guides you can accomplish this job without formatting.

When I search this title, I found many articles explained how to merge partitions Windows 7 with Disk Management. Some of which is really useful if you read the article through, but some may be hard to understand. In fact, it’s not that hard to combine two partitions into one Windows 7. You don’t have to read many long web or many pages to do this simple job if you are using this software I’m going to write about.

Combine Merge Partitions Windows 7 with Existing Partition

To merge 2 partitions Windows 7, for example: I got 61 GB on C: drive and 135 GB on E: partition, now I want to add E partition to C. How to operate? Okay, first to run AOMEI Partition Assistant on desktop, then choose C, and there are two ways of choosing Merge Partitions: one is right click on C drive and select it, the other is directly choose it from the partition operations list on the left.

Then in the pop-up window you can see E partition is in the list, check it to proceed.

Don’t forget to Click Apply at last.

Combine Merge Partitions Windows 7 with Unallocated Space

Maybe adding 135 GB to C drive is too much, and the free space are not used for data. How about adding 10 GB to system partition? It’s not a problem for PA, in that case, we need to split 10 GB from E partition, chick on it, and choose Resize/Move Partition on the left.

Resize Partition

Slide the bar on the left or right (I suggest you to slide the left one, explanation follows in the end of the part). Stop sliding when you see the unallocated space goes for 10 GB. Click OK. Now we have space to merge.

Shrink Partition

Repeat the first method: choose C drive, select Merge Partition, check on unallocated space, Click OK to continue.

Merge Unallocated Space into C

Before you apply these operations, you can see the Pending Operations down left: 1. Move and Resize (E:) on disk 1. 2. Resize (C:) on disk 1.

Now you can Apply them. In the whole progress, data will not be formatted nor deleted nor disappear.

  • The suggestion I made in the second paragraph on sliding the left bar to resize is mainly because the unallocated space better be right behind the target partition. It’s also OK to slide the bar on the right, but by then you can see 3 pending operations list down left, which added Move (E:) on disk 1.

  • In windows 7 the “system reserved” partition could not be merged. Thus, you can only merge other partitions into system partition but can't merge system partition into data partition.

  • You can merge several part of unallocated space into an existing partition at once, but you can only merge one exsiting partition to aim existing partition at once.

There are functions listed in the disk operations, like split partition, create partition, delete partition. etc. Click the following pictures to download and learn more.
