The filing system that is primarily used for large USB flash drives is the NTFS file system. Well the NTFS is a “Hot- Swapping” system unlike the FAT32 file system which is recommended for hard disk only. But you can format the flash drive using FAT32 file system.
The filing system NTFS provides better security, support for large drives, and access to users. There is different levels of access for users using the NTFS system. NTFS partial limited to the same size drive as FAT32 but it is theorized that NTFS can partition a drive to 16 exabytes which is 16 billion billion bytes. Finally the NTFS system uses EFS (Encrypting File System) where all the files are encrypted without the use of a username and password.
Actually FAT32 is not preferred over NTFS, NTFS is preferred over FAT32 for newer system like Windows 2000, XP, Vista, Windows7, etc. Since this day in age the way we move information from place to on USB flash drives or micro SD cards NTFS is a better system. Also with the ability to partition larger drives that was not even thought of back when FAT32 was introduced. When the largest drives were in GBs for a home computer but now we have TBs in a standard computer today. The security features that is associated with the NTFS file system wasn’t even really need back in 1995. When the computer was just then starting to take off, where today everyday life revolves a computer.
