This module is mainly used to create Windows partition on a Mac drive, so that you can get the opportunity to run even windows OS while using Mac for plenty of purposes.

At times, initially created Boot Camp partition needs more space, therefore in order to enlarge the size people often format their boot camp drive and recreate it with more space. This process is actually recommended by Mac as Disk Utility can resize an HFS+ (Mac OS) partitions, but not capable enough to revise the size of NTFS partitions.
