I want to write a Windows 10 ISO on an empty 16gb USB Drive

  • Tried to Download Windows 10 ISO to reload Windows. The size of the ISO is ~ 5gb. Using an empty 16gb USB, Three times Windows say "TOO LARGE for destination file system. The USB is a FAT32. Finally, downloaded to my root HD and yes, the ISO's are ~ 5gb. But Windows still refuses to COPY this file to the 16gb USB.

    Anyone know why? Should I try to define the USB as NTFS?
