How to Create Extra Partition on Your Computer Hard Drive?

Windows users should be very clear that if there no unallocated space on the hard drive, you can't use the built-in disk management tool to create a new partition. So what do you do with the absence of unallocated space? You have to shrink one volume and allow a free space first. Since disk management does not support FAT partition resize by extending or shrinking, we suggest you use the best Windows disk management alternative to create an extra and new partition disk, which will make the process easier and faster.
