exFAT File System - QNAP


exFAT Ready NAS

Speeds Up Large Media File Transfer

exFAT is a file system developed by Microsoft® that is optimized for providing fast and high-capacity flash memory (such as SD cards or USB devices). With high-resolution media (such as 4K) now in our everyday lives, QNAP now provides an official exFAT driver that provides compatibility for exFAT-based devices with QNAP NAS.

exFAT - the Next-generation File System

Photographers, videographers, and other creators often run into the limits of conventional FAT32-based storage. With the potential of 4K video files to exceed hundreds of gigabytes, FAT32's 4GB single file limit makes it ill-suited for high-resolution media files. With exFAT supporting files up to 16EB, you don’t need to break files into multiple smaller ones, eliminating the risk of file loss and minimizing waiting times when transferring larger files from the USB drives/SD cards to NAS.

Smoother Media Editing Experience

Starting from QTS 4.3.0, you can purchase an exFAT license from the QNAP License Store. Once the license is installed, you can directly copy and edit files that are stored on exFAT-based storage devices after it is connected to a compatible QNAP NAS. This not only helps you to quickly transfer media to the NAS and start editing right away, but it also allows you to instantly browse the content using multimedia applications such as Photo Station and Linux Station.
