'''Filesystem in Userspace''' ('''FUSE''') is a [[software interface]] for [[Unix]] and [[Unix-like]] computer [[operating system]]s that lets non-privileged users create their own [[file system]]s without editing [[kernel (operating system)|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.

FUSE is available for [[Linux]], [[FreeBSD]], [[OpenBSD]], [[NetBSD]] (as [[PUFFS (NetBSD)|puffs]]), [[OpenSolaris]], [[Minix 3]], [[macOS]],<ref>{{cite web|url=https://osxfuse.github.io/|title=Home - FUSE for OS X}}</ref> [[MorphOS]] (as filesysbox.library), and [[Microsoft Windows|Windows]].<ref>{{Citation|last=Zissimopoulos|first=Bill|title=billziss-gh/winfsp|date=2021-02-14|url=https://github.com/billziss-gh/winfsp|access-date=2021-02-16}}</ref>
