Why need to add more storage to Windows 10?

Insufficient computer storage space is often the main culprit for Windows 10 slowing down. Because when PC storage space is insufficient, its operating speed, performance and ability to maintain system integrity will be affected. A hard drive with insufficient capacity almost no space to install new versions of Windows 10 or other programs, which will seriously degrade the user experience over time.

But don’t worry, we have some ways to solve this problem. In addition to freeing up disk space, we can also add more storage to Windows 10. In this article, we will discuss several methods of how to get more storage on Windows 10.

Method 1. Add storage via resize partition

The first method is to add the unallocated space adjacent to the system drive to the system drive, you can also use this function to shrink partition. Just three steps to complete.

Step 1. After making preparations, run AOMEI partition Assistant Professional. In the main interface, you can see all the hard disks on the computer and the partitions on different hard disks. Then right-click your system disk (this article take C drive as an example) and select Resize/Move Partition.

Step 2. In this step, you can drag this button to increase the space required by the system drive and click OK.

Step 3. You can preview that all the unallocated space on the right has been added to the C drive. Don’t forget to click Apply to generate the operation.

Method 2. Get more space with merge partition

Is the first method simple? But what you need to pay attention to is that there must be adjacent unallocated space on the left or right sides of your system drive. If your unallocated space is not adjacent, you can add storage through Merge Partition. This function can merge non-adjacent unallocated space with the system drive, or even merge unused adjacent partitions with the system drive.

Step 1. Same as method one, right-click C drive and select Advanced> Merge Partitions.

Step 2. Select a non-adjacent unallocated space or an adjacent partition (if this partition has data, then the data in the partition will be merged into the C drive), and click OK.

Step 3. Click Apply, you will see the C drive has been extended.

Method 3. Allocate storage from D drive to C

If you don’t have unallocated space, and you don’t want to merge other partitions with C drive too. Then the third method allows you to directly allocate the extra free space of D drive to C drive. The specific steps are as follows:

Step 1. In the main interface of AOMEI Partition Assistant Pro, select “Allocate Free Space”. 

Step 2. Then type in the size of the free space which you want to cut from D drive and this free space will be directly added into the C drive.

Step 3. You can take a preview of the operation result before confirming start. Click “Apply” to execute this operation.
