Filesystem in Userspace (FUSE) is a loadable kernel module for Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a "bridge" to the actual kernel interfaces.
Released under the terms of the GNU General Public License and the GNU Lesser General Public License, FUSE is free software. The FUSE system was originally part of A Virtual Filesystem (AVFS), but has since split off into its own project on SourceForge.net.
FUSE is available for Linux, FreeBSD, NetBSD (as puffs), OpenSolaris, and Mac OS X[1]. It was officially merged into the mainstream Linux kernel tree in kernel version 2.6.14.[2]

[edit] Virtual file system
FUSE is particularly useful for writing virtual file systems. Unlike traditional file systems that essentially save data to and retrieve data from disk, virtual filesystems do not actually store data themselves. They act as a view or translation of an existing file system or storage device.
In principle, any resource available to a FUSE implementation can be exported as a file system.
[edit] Examples
- Wuala: A multi-platform, Java-based fully OS integrated distributed file system. Using FUSE, MacFUSE and Callback File System respectively for file system integration, in addition to a Java-based app accessible from any Java-enabled web browser.
- MyVDrive: Fully OS integrated Internet file system using FUSE
- WebDrive: A commercial filesystem implementing WebDAV, SFTP, FTP, FTPS and Amazon S3
- Transmit: A commercial FTP client that also adds the ability to mount WebDAV, SFTP, FTP and Amazon S3 servers as disks in Finder, via MacFUSE.
- ExpanDrive: A commercial filesystem implementing SFTP/FTP/FTPS using FUSE
- GlusterFS: Clustered Distributed Filesystem having capability to scale up to several petabytes.
- SSHFS: Provides access to a remote filesystem through SSH
- FTPFS
- GmailFS: Filesystem which stores data as mail in Gmail
- GAEDrive: A Network Storage based on Google App Engine
- gae-filestore: Virtual File System library on Google App Engine
- GVFS: The virtual filesystem for the GNOME desktop
- EncFS: Encrypted virtual filesystem
- NTFS-3G and Captive NTFS, allowing access to NTFS filesystems
- exFAT: The Extended File Allocation Table file system from Microsoft
- WikipediaFS: View and edit Wikipedia articles as if they were real files
- Sun Microsystems's Lustre cluster filesystem will use FUSE to allow it to run in userspace, so that a FreeBSD port is possible.[3] However, the ZFS-Linux port of Lustre will be running ZFS's DMU (Data Management Unit) in userspace.[4]
- archivemount
- LoggedFS: Logging of file system access
- HDFS: FUSE bindings exist for the open source Hadoop distributed filesystem.
- mtpfs: mounting MTP devices like Creative Zen music players
- Sector File System: Sector is a distributed file system designed for large amount of commodity computers. Sector uses FUSE to provide a mountable local file system interface.
- CurlFtpFS Filesystem to access FTP/SFTP locations.
- fuse-ext2 An open source ext2/ext3 file system. (Supports Mac OS X 10.4 and later (Universal Binary), using MacFuse)
- Lessfs: inline data de-duplicating filesystem for Linux that includes support for lzo or QuickLZ compression and encryption.
- CloudStore (formerly, Kosmos filesystem): By mounting via FUSE, existing Linux utilities can interface with CloudStore.
- MooseFS: An open source distributed fault-tolerant file system available on every OS with FUSE implementation (Linux, FreeBSD, NetBSD, OpenSolaris, MacOS X), capable of storing petabytes of data spread over several servers visible as one resource.
- NagusFS: Filesystem representation of Nagios services.
