ExFat File System
ExFAT (Extended File Allocation Table) is a file system used
for storing data on devices like flash drives, digital cameras, and mobile
phones:
Storage capacity
ExFAT can store larger files than the FAT32 file system,
with a 4 GB file size limit.
Compatibility
ExFAT is compatible with most Windows and Mac operating
systems, though older versions may need an update.
Default file system
ExFAT is the default file system for SDXC and SDUC cards larger than 32 GB.
Other devices
ExFAT is also used in smart televisions, portable music
and video players, and media centers.
Some things to keep in mind about exFAT include:
Not journaled
ExFAT is not journaled, so if you eject the drive
incorrectly while reading or writing, you might lose data or corrupt the drive.
Not compatible with some older devices
ExFAT isn't compatible with some older devices.
Not suitable for intensive applications
ExFAT can have problems with intensive applications, and it
can take several attempts to transfer data correctly.
Data loss
Since exFAT doesn't redundantly store master data, you
should carefully remove storage media with the exFAT file system.
