Editing Filesystem in Userspace (section)

== Applications ==

=== On-disk file systems ===
Conventional on-disk file systems can be implemented in user space with FUSE, e.g. for compatibility or licensing reasons.

*[[Linear Tape File System]]: Allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives.
*[[NTFS-3G]] and [[Captive NTFS]], allowing access to [[NTFS]] filesystems.
*[https://github.com/jaylogue/retro-fuse retro-fuse]: retro-fuse is a user-space filesystem that provides a way to mount filesystems created by ancient Unix systems on modern OSes. The current version of retro-fuse supports mounting filesystems created by Fifth, Sixth and Seventh Edition of Research Unix from [[Bell Labs]], as well as 2.9BSD and 2.11BSD based systems.

=== Layering file systems ===
FUSE filesystems can create a view of an underlying file system, transforming the files in some way.

*[[EncFS]]: [[Disk encryption|Encrypted virtual filesystem]]
* FuseCompress, gzipfs, Fuse-ZIP, CompFUSEd: Compressed virtual filesystems
* Archive filesystems may also perform this task

=== Archive and backup file systems ===
FUSE filesystems can expose the contents of archives or backup sets without having to first extract them.

*[[archivemount]]
