How to Change Partition Size in Windows 8 without Losing Data?

Question: Change Size of Windows 8 Hard Drive Partition?

I partitioned my Windows 8 hard drive into two with one partition being about 30 gigs and the other partition being about 270 gigs. Since the smaller partition is where all the Windows 8 stuff resides, including the program folder, I am finding that this smaller partition is quickly running out of space. Is there a way to extend the boot partition(or sysetm partition, c drive) bigger? I am also afraid to move some of the program folders as I fear moving the folder will disable some of the programs.

Do you encounter the similar problem in Windows 8? If the system partition is running out of space and struggles for precious free space, you are unable to download Windows 8 updates and install new applications, even the whole performance of your PC will be declined. In other words, the computer goes much slowly.

Can I use Disk Management to change partition size in Windows 8?

Although Windows 8 Disk Management provides extend and shrink volume features, you may find extend volume greyed out. In other words, you can not shrink one partition and add the unallocated space generated from the partition to another. Because extend volume option only works with contiguous unallocated space at the right side of the partition you want to extend.
