Introduction of Free Space

Free space, also called free capacity or unused space, is the rest amount of stored information of a partition. The difference between unallocated space and free space is that, free space is space available within a partition and you can not use Windows 8 built-in disk management tool to create a new partition in free space or merge free space to another partition directly. But, this article is going to discuss how to reallocate free space from one partition to another in Windows 8 with free partition software, and on the condition that need not switch free space to unallocated space.

Why need to move free space in Windows 8?

The space of C drive which you allocate is reasonable in your mind when partitioning a hard disk in windows 8. But, when C drive is nearly full of Windows 8 and some other programs, it will run out of space and the available space is on the decline. Then your computer will perform under low disk space and you will have bad mood due to the low computer speed. However, the contiguous partition D has enough unused space, is there a method that can help you move free space from D drive to C drive?

The answer is yes, but some users begin to check their programs and uninstall the programs that they don’t use frequently. This will make you get out of the problem for a short time. Because your data is increasing day by day and after a time the same problem will come out again. Then the users may use the Windows 8 built-in tool—Disk Management to extend C drive. However, they eventually find that they are unable to transfer the free space in D partition to C drive with Disk Management. So what is the way can help you solve the problem freely?
