How to Split Partition Without Losing Data?

AOMEI Partition Assistant could be your ideal choice to split partition without losing data as well as resize/merge partitions easily, etc in Windows.

Necessity of splitting partition

Most users find there’s only one partition when they buy a new PC. In this case, it’s very necessary for you to split partition without losing data. Because having system programs and personal data in one partition is not safe. You may possibly need to reinstall system if your computer is under virus attack so that you could lose all personal data. On the contrary, if there are two or more partitions, you won’t have to worry about such kind of problems. Besides, splitting partition helps you store and search files more efficiently.

How can I split partition without losing data?

Two ways are available here to split partition without losing data. First, as know, Windows has a built-in disk managing tool - Disk Management. You’re able to split partition by shrinking volume with it. However, some limitations exist. For example, you can not shrink a volume beyond the point where any unmovable files are located, which means there’s a chance that you can’t decide the size of a new partition or you won’t be capable of resizing partition at all. So, another third-party software is recommended - AOMEI Partition Assistant.

Split partition with AOMEI Partition Assistant

AOMEI Partition Assistant is a powerful and easy-to-use disk/partition software that enables you to split partition without data loss in Windows 7/8/10/XP as well as Vista. Let’s see how it works.

Step 1: Install and launch AOMEI Partition Assistant.

Step 2: Select the partition you’re going to split. Click “Split Partition” on the left side. Also, it’s OK to choose the feature from the contextmenu.

Step 3: In the pop-up window, drag the border to specify the size. By the way, when you’re splitting partition on an SSD, ticking the box down there can optimize its performance.


Step 4: If you want to split more, just do the same. Pending operations will be listed in the main interface. You’re allowed to “Apply” for final execution.


Tips: Feature “Resize Partition” also works well to split partition without losing data. Plus, operations will be performed under PreOS Mode and your computer will reboot if the process involves system partition.
