exFAT is the modern version of its predecessor - the FAT filesystem. It expands the size of files that flash memory devices can handle, to a great extent. The exFAT file system facilitates large files for use of audiovisual media, seamless data portability and an easy interchange between desktop PCs and consumer electronic devices. Here are a few finer points of the exFAT system:

• Increasing of support from 32 GB up to 256 TB

• Supports storage of more than 4,000 RAW images, 100 high-definition (HD) movies, or 60 hours of HD recording in a single directory

• Speeds up file saves of Secure Digital Extended Capacity (SDXC) cards to achieve their full 300MBps speed
