Divide a USB flash drive (pendrive) into two or more partitions, just like a hard drive or SSD.

DiskPart can also create multiple partitions:

1. diskpart
2. list disk
3. select disk X
4. clean
5. create partition primary size=8000
6. format fs=exfat quick
7. assign
8. create partition primary
9. format fs=ntfs quick
10. assign
11. exit

Replace X with your USB disk number and 8000 with the desired size (in MB).
