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.
