During the format process, only the best suited file systems will be displayed in Windows.įirst, let me say it IS possible for Windows to format a USB flash drive as UDF (Universal Disk Format). Windows provides NTFS as an option for USB flash drives, but as mentioned before, NTFS is not the best file system for a USB drive. The proper file systems for a flash drive is: FAT, FAT32 or exFAT.
