AOMEI Partition Assistant helps you resize partition in Windows 8 on 32 bit and 64 bit without reinstalling system. Free download this partition assistant to perfect your computer performance.

Scenario: My DELL laptop has 30GB in C drive, but it only has little free space in drive C now. I wonder how to enlarge Windows 8 system (C) partition without reinstalling operating system? My D drive has more than 50GB free space, so I decide to allocate some space to system drive from drive D. I have tried to solve this problem with Partition Magic, but unfortunately, it can not work in Windows 8.

Partition Magic is the product of Symantec, and it was initially made by PowerGuest. However, it does have some limitations, such as, it just work in Microsoft Windows 98, 2000, NT, ME and XP. So it can not be processed in Windows 8.

Compared with Windows XP, the built-in Disk Management of Windows 8 does make some breakthroughs. It has the functions of shrinking and extending volume, meanwhile, it still has many limitations. However, AOMEI Partition Assistant is a well-operated partition tool. Here comes a comparison between AOMEI Partition Assistant and Windows 8 built-in Disk Management.
