Perhaps you are curious about why someone would like to resize a Windows partition. One reason may be if you wish to set up another operating system, but do not have sufficient unallocated space to create a new partition for it. Don’t worry. You can avoid such problem under the help of Partition Assistant. It can shrink the big capacity of partition (such as shrink a NTFS partition) to provide enough space to create new partition.

Here I would like to tell you some information about the NTFS. It is short for "New Technology File System", which is the standard file system of Windows NT, and includes later versions Windows 2000, Windows XP, Windows Server 2003, Windows Server 2008, Windows Vista and Windows 7. Compare with FAT file system, it is regarded as the better file system for Microsoft's Windows operating systems.

Now I will show you the process to shrink NTFS partition:
1. Download the Partition Assistant and install it.
2. Then you will see a screen as follows, that is a case of the partition before change.
