Sometimes we need split large storage on USB stick to get FAT32 file system (for some TV or old operation systems).
You can do it with windows utility – diskpart.
Run command prompt with admin rights. Enter diskpart. List available disk and find you USB stick:
Select required disk
select disk 2
Add new primary partition with limited size (in megabytes, 4GB for example). You can choose up to 16GB partition for FAT32 with backward comparability with old operation systems.
create partition primary size=4096
Format it after selection (and assign drive letter).
select partition 1 format fs=fat32 quick assign letter (drive letter)
Exit from diskpart and enter again. Select disk from last operation and create second primary partition with remaining size.
create partition primary
Format second partition from diskpart after selection (and assign drive letter).
select partition=2 format fs=exfat quick assign letter (drive letter)
