GPhotoFS is a FUSE file system module to mount your camera as a file system on Linux. This allow using your camera with any tool able to read from a mounted file system.

dbxfs allows you to mount your Dropbox folder as if it were a local file system using FUSE.

fscrypt is a high-level tool for the management of Linux native filesystem encryption. It manages metadata, key generation, key wrapping, PAM integration, and provides a uniform interface for creating and modifying encrypted directories.

TMSU is a tool for tagging your files. It provides a simple command-line utility for applying tags and a virtual file system to give you a tag-based view of your files from any other program. TMSU does not alter your files in any way: they remain unchanged on disk, or on the network, wherever your put them. TMSU maintains its own database and you simply gain an additional view, which you can mount where you like, based upon the tags you set up.

This package provides Snapper, a tool that helps with managing snapshots of Btrfs subvolumes and thin-provisioned LVM volumes. It can create and compare snapshots, revert differences between them, and supports automatic snapshots timelines.

AVFS is a FUSE-based filesystem that allows browsing of compressed files. It provides the mountavfs command that starts a small avfsd daemon. When a specially formatted path under ~/.avfs is accessed, the daemon provides listings and content access on the fly. The canonical form of virtual file name is:

[basepath]#handler[options][:parameters][/internalpath]

Example file names:

• ~/.avfs/home/user/archive.tar.gz#ugz#utar/path/file

• ~/.avfs/#http:localhost|some|path

emacs-dired-hacks has dired-avfs module which enables seamless integration with avfs.

LIBNFS is a client library for accessing NFS shares over a network. LIBNFS offers three different APIs, for different use :

1. RAW, a fully asynchronous low level RPC library for NFS protocols. This API provides very flexible and precise control of the RPC issued.

2. NFS ASYNC, a fully asynchronous library for high level vfs functions

3. NFS SYNC, a synchronous library for high level vfs functions.

This package provides the bcachefs command-line tool with many subcommands for creating, checking, and otherwise managing bcachefs file systems. Traditional aliases like mkfs.bcachefs are also included.

Bcachefs is a CoW file system supporting native encryption, compression, snapshots, and (meta)data checksums. It can use multiple block devices for replication and/or performance, similar to RAID.

In addition, bcachefs provides all the functionality of bcache, a block-layer caching system, and lets you assign different roles to each device based on its performance and other characteristics.

NILFS is a log-structured file system supporting versioning of the entire file system and continuous snapshotting, which allows users to even restore files mistakenly overwritten or destroyed just a few seconds ago.

This package provides an implementation of overlay+shiftfs in FUSE for rootless containers.

This package provides an implementation of the exFAT file system, including command-line tools to validate exFAT file systems and to create new ones.

These are command-line user space tools for the exFAT file systems. Included are mkfs.exfat to create (format) new exFAT file systems, and fsck.exfat to check their consistency and repair them.

OpenZFS is an advanced file system and volume manager which was originally developed for Solaris and is now maintained by the OpenZFS community.

This is a file system client based on the FTP File Transfer Protocol.

Squashfuse lets you mount SquashFS archives in user-space. It supports almost all features of the SquashFS format, yet is still fast and memory-efficient.

httpfs2 is a fuse file system for mounting any HyperText (HTTP or HTTPS) URL. It uses HTTP/1.1 byte ranges to request arbitrary bytes from the web server, without needing to download the entire file. This is particularly useful with large archives such as ZIP files and ISO images when you only need to inspect their contents or extract specific files. Since the HTTP protocol itself has no notion of directories, only a single file can be mounted.

udftools is a set of programs for reading and modifying UDF file systems. UDF is a file system mostly used for DVDs and other optical media. It supports read-only media (DVD/CD-R) and rewritable media that wears out (DVD/CD-RW).

BEES is a block-oriented, user-space deduplication agent designed for large btrfs file systems. It combines off-line data deduplication with incremental scanning to minimize the time your data spend on disk between being written and being deduplicated.

Watcher may be used as a library or a program that can be used to efficiently watch a file system for changes. This package provides the following components:

include/wtr/watcher.hpp

C++ header library

watcher-c

C shared and static library

wtr.watcher

Command-line interface (CLI)

tw

Minimal, more human-readable CLI variant

mergerfs-tools is a suite of programs that can audit permissions and ownership of files and directories on a mergerfs volume, duplicates files and directories across branches in its pool, find and remove duplicate files, balance pool drives, consolidate files in a single mergerfs directory onto a single drive and create FreeDesktop.org Trash specification compatible directories.

Libeatmydata transparently disables most ways a program might force data to be written to the file system, such as fsync() or open(O_SYNC).

Such synchronisation calls provide important data integrity guarantees but are expensive to perform and can significantly slow down software that (over)uses them.

This price is worth paying if you care about the files being modified---which is typically the case---or when manipulating important components of your system. Please, do not use something called ``eat my data'' in such cases!

However, it does not make sense to accept this performance hit if the data is unimportant and you can afford to lose all of it in the event of a crash, for example when running a software test suite. Adding libeatmydata.so to the LD_PRELOAD environment of such tasks will override all C library data synchronisation functions with custom no-op ones that do nothing and immediately return success.

A simple eatmydata script is included that does this for you.

This package provides statically-linked jfs_fsck command taken from the jfsutils package. It is meant to be used in initrds.

Gocryptfs is an encrypted overlay filesystem written in Go. It features a file-based encryption that is implemented as a mountable FUSE filesystem.

Gocryptfs was inspired by EncFS and strives to fix its security issues while providing good performance. Gocryptfs is as fast as EncFS in the default mode and significantly faster than paranoia mode in EncFS, which provides a security level comparable to Gocryptfs.

On CPUs without AES-NI, gocryptfs uses OpenSSL through a thin wrapper called stupidgcm. This provides a 4x speedup compared to Go's builtin AES-GCM implementation.

FSArchiver saves the contents of a file system to a compressed archive file, and restores it to a different file system and/or partition. This partition can be of a different size than the original and FSArchiver will create a new file system if none exists.

All standard file attributes supported by the kernel are preserved, including file permissions, timestamps, symbolic and hard links, and extended attributes.

Each file in the archive is protected by a checksum. If part of the archive is corrupted you'll lose the affected file(s) but not the whole back-up.
