exFAT
Built to handle the demands of today’s digital media, exFAT enables seamless file transfer and storage using permanent or removable media, regardless of device or operating system.
Read our exFAT specification
Extended File Allocation Table (exFAT) is Microsoft-patented file system. exFAT can handle extremely large file sizes and enables seamless file exchange between devices that use removable storage, regardless of device or operating system. Combining wide interoperability with the capacity to handle files at virtually unlimited scale, exFAT is a must-have tech licensing program for companies seeking an efficient file storage and transfer solution.
Enables virtually unlimited card storage
exFAT allows devices to handle growing requirements for media file storage, increasing volume capacity into the terabytes. exFAT also allows for single files to exceed 4 GB, a limitation of FAT32.
Provides an extensible format
The extensible format includes OEM-definable parameters to customize the file system for specific devices.
Interoperability of systems and devices
exFAT supports interoperability with a very wide range of operating systems, avoiding the need to constantly reformat files and media.
Enables fast transfer speeds
With modern storage allocation techniques, file saves can achieve their full speeds.
exFAT as part of the Linux kernel
In August 2019 Microsoft announced its support for integrating exFAT into the Linux kernel. exFAT is now part of the Linux kernel 5.7 and devices using this code are covered under the GPLv2 license.
