Why Need to Change Partition Size?

Some frequently used partitions are easily running out of space, such as system partition, for the default storage location of downloaded files and installing programs is always system C drive. Most users will keep default settings instead of specify a new location. Therefore, system partition will run out of space soon. While, other partitions are full of free space and some are even empty.

In such situation, change partition size is a good solution for unbalanced free space allocation. Users can shrink one or more other partitions to get some unallocated space, and extend C partition with the unallocated space.

Another Easier Way to Resize Partition

There’s a third party software named AOMEI Partition Assistant which can easily extend or shrink partition without limitation. It is one of the best alternative of Disk Management. Download, install and launch it on your computer to get ready to resize hard disk partitions.

  • Shrink Partition

    AOMEI Partition Assistant “Resize Partition” feature can assist you to shrink any partition as much as you can. That is, it will shrink all the free space out only if you would like to. Besides, during shrinking, you can decide where the generated unallocated space locates, before or behind the original partition. Moreover, you can continue to adjust the location of the unallocated space using " Move Partition" feature after shrinking.

    How It Works

    Tip: For partitions on MBR disk, they can be extended relying on another feature of AOMEI Partition Assistant – Extend Partition Wizard.

  • Extend Partition

    “Resize Partition” feature of AOMEI Partition Assistant can also help you to extend partitions which are running out of space, especially for system partition. It can extend system partition with any unallocated space on the same hard drive. If the unallocated space isn’t very behind C Partition, you can move it and make it is. When you are informed by "low disk space" problem, you can make use of this function to solve it.

"I have a problem with resizing my partition C on Windows 8.1. It only has 28 GB and I have run out of every space. The Disc manager for resizing partitions is not working (every option for a Disc C is greyed out). I downloaded three partition managers: Paragon, Aomei and one more (don't remember the name, cause I deleted it already). All of them were supported by Windows 8.1 32 bit. And still it was not possible to do anything with the disk C, even though I have a lot of unallocated space to use. "

"I used aomei partition assistant before in my windows 8.1, it worked well. do you use "resize partition" in aomei partition assistant to extend you c drive? if you do like this, the unallocated space on your hard disk should be contiguous behind the partition c, or you can't extend partition. but if the unallocated space is not contiguous behind partition c, you an use extend partition wizard or merge partitions to extend partition c"

"So far it hasnt been a big issue- we've had to periodically clean junk off of the C drive in order to make room for installing updates and such, but it hasnt been a big deal. Now its getting to the point where there almost isnt room to install updates, and its getting annoying having to manage down to the last MB of data on the drive just to keep some free space on it. How would you guys handle this?"

"Old thread, but I have to say, I used AOMEI Partition Assistant Lite (Free, windows server) on an old 2003 Server for the first time today and it is nothing less than awesome, I have a new favorite partition management utility, and it's FREE. Even licensing it is cheap. Cannot say enough good things."

"I am running out of space on my 12 gig system partition. After some work i got it back up to 1 gig of free space but it won't be long before it will be getting low again. I have a d: partition with about 40 gig of free space. I am running SBS 2003 and if i understand correctly, it offers no utility that will let you resize the system partition. does anyone have experience using 3rd party partitioning software like this? does it do what it claims etc ...."

"disk management is a built-in tool in server 2003 which allows you to extend/shrink partition without software. but with this tool, you should know that the extend volume cab be used only when there is unallocated space contigugous behind the partition you need to extend. if you can't satisfy the precondition. you may need third party software such as aomei partition assistant server. this software can resize your partition without data loss."
