How to Combine or Merge Partitions in Windows 7 Without Formatting

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

Hard Drive Partition Tool-Partition Assistant

To merge partition hard disk, for example: I got 20 GB on C: drive and 80 GB on D: partition, now I want to add D partition to C. How to operate? Okay, first to run 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 D partition is in the list, check it to proceed. Don’t forget to Click Apply at last.

Maybe adding 80 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 D partition, chick on it, and choose Resize/Move Partition on the left, slide the bar on the left or right (I suggest you to slide the left one, explanation follows in the next paragraph). Stop sliding when you see the unallocated space goes for 10 GB. Click OK. Now we have space to merge. Repeat the first method: choose C drive, select Merge Partition, check on unallocated space, Click OK to continue. Before you apply these operations, you can see the Pending Operations down left: 1. Move and Resize (D:) 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 must 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 (D:) on disk 1. Another thing should be noticed is that in windows 7 the “system reserved” partition could not be merged.

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.
