This free partition tool will allow you to shrink/extend partitions on your hard drive if you are running out of space on your main partition. Say for instance you have 1TB drive and partition it into 2 drives such as 100 gb and 900gb. Later on you realize that you are running out of space on the 100gb partition that windows and your games/applications are installed on. Just download this program and extend the main partition and have it take space from the second partition. Once you apply what you want done, it will do it automatically and reboot the system. This tool will also convert MBR to GPT or vice versa, lets you migrate OS from HDD to SDD, can convert the file system used and surface test of drive to test for error. And much more...
