exFAT

Information about exFAT

exFAT (Extended File Allocation Table) is a file system suited especially for flash drives introduced with Windows Embedded CE 6.0. exFAT is used where the NTFS file system is not a feasible solution, due to data structures overhead.

The advantages over existing File Allocation Table versions include:
  • theoretical file size limit of 264 bytes (16 Exabytes), limit lifted from 232 bytes (4 Gigabytes)
  • cluster size of up to 2255 bytes, implementation limit of 32MB
  • free space allocation performance improved due to introduction of a free space bitmap
  • support for more than 1000 files in a single directory
  • support for access control lists
  • support for Transaction-Safe FAT File System (TFAT) (optionally WinCE activated function)
Windows Vista Service Pack 1 adds support for exFAT.[1]
