Filesystem in Userspace

A flow-chart diagram showing how FUSE works
Developer(s)	Miklos Szeredi
Stable release	2.9.3 / 1 July 2013; 8 months ago
Written in	C
Operating system	Unix-like
Type	File system driver
License	GPL for kernel part, LGPLfor Libfuse
Website	fuse.sourceforge.net

Filesystem in Userspace (FUSE) is an operating
system mechanism 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.
The original, and commonly used implementation, is implemented as a loadable
kernel module. Released under the terms of the GNU
General Public License and the GNU
Lesser General Public License, FUSE is free software. This implementation
of FUSE is available for Linux, FreeBSD, NetBSD (as puffs),OpenSolaris, Minix
3, Android and OS
X.[1]

Virtual file system[edit]

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.

Example uses[edit]

copy-fuse:
A Python FUSE layer for accessing files stored on Copy.com.
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.
