After I installed macOS Sierra I decided I wanted to also have Windows for gaming. I installed Windows 8.1 via Boot Camp Assistant and gave it about 110 GB of space.
After some time I realized that I don't have enough space left so I made a partition via Disk Utility that had about 150 GB of size and it's formatted as ExFat.
I went back to Windows but unfortunately, the new partition is nowhere to be seen in File Explorer or Disk Management.
I tried using MS-DOS (FAT) with no luck.
I would love to do this without reinstalling Windows if possible.
