Partition Magic is the software to resize partition. But this software is not free.
There is an alternative I found from Internet you can try which is freeware, I have used Partition Magic many years but not the Partition Logic. Use it with caution.

Warning: resize partition is a high risk task, do it wrong can end up all data lost. So, backup your data and understand all steps before any action.
