This feature will review the available disk space and then allow you to specify the amount to "Shrink" on the volume. In most cases, the amount allowed to "Shrink" is minimal, which is due to system files on your hard disk that are locked in position and restricting the Shrink feature from giving you more available space.

There is a great article found here that can give you more information on this issue, and a common MFT file issue that may require some attention. The logic is to defragment and re-structure all the files on your hard disk so that they are located at the beginning of your disk partition. This will allow the Shrink feature to recognize a large amount of "Free Space" that will be available for shrinking.

The defragmenting process is the key to shrinking your volume, and the PerfectDisk tool is the only one that can carry you through this process. There are some system files that are locked by windows once the system is booted, and windows seems to want to continually write these files into blocks toward the middle and end of your hard disk partition.
