Step 5: Split Install.wim and Make USB Bootable

For latest Windows 10 or Windows 11 ISO, which contains a large install.wim file (> 4GB), UUByte ISO Editor will split it automatically at the end of burning process. This make sure the install.wim file sits well on a FAT32 partition after shrinking. This extremely important on Mac as it can not read NTFS partition by deafult. Only FAT32 is available for creating Windows bootable USB.
