Connecting USB Drive to iPhone, formatting problems

I want to view files on my USB stick which are larger than 4GB so the USB stick is NTFS form. When I connect and look at the drive in my files app it says it's "read-only", so I couldn't view the files. I read elsewhere that this is because the drive needs to be in FAT32 form. But I cannot load the files onto the drive if it is in FAT32 because it doesn't allow anything larger than 4GBs.

I seem to be a bit stuck here. What can I do?
