ExFAT project member Andrew Nayenko has released version 1.0.0 of fuse-exfat, a filesystem driver that can read and write to Microsoft's exFAT (Extended File Allocation Table) filesystem. Like the Ntfs-3G NTFS driver that is used in Linux distributions, the exFAT driver is based on FUSE (Filesystem in Userspace) and works under Linux as well as OS X. In a short test with Fedora 18, reading from and writing to a USB flash drive that was freshly formatted with exFAT worked fine.
The exfat-fuse driver took three years of development time and nine beta versions to reach version 1.0.0. In addition to the driver, the exFAT project also offers an exfat-utils package to download that includes programs for creating and checking exFAT drives. Like the driver, the tool collection is released under the GPLv3 licence.
