This package provides several command-line tools to transform a supported file system, such as XFS, into one of a different supported type, such as ext4. All existing file contents, names, and directories are preserved.

The conversion happens in place, without the need to create a complete copy of the original data. This lets you transform almost full file systems on systems where adding (sufficient) additional storage space is not an option.

Do not use this package when you could simply create an empty file system from scratch and restore from a back-up. Transformation is limited, slow, and significantly increases the risk of irreversible data loss!

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

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.

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.

The FSQA regression test suite, more commonly known as xfstests, comprises over 1,500 tests that exercise (torture) both the user- and kernel-space parts of many different file systems.

As the package's name subtly implies, it was originally developed to test the XFS file system. Today, xfstests is the primary test suite for all major file systems supported by the kernel Linux including XFS, ext4, and Btrfs, but also virtual and network file systems such as NFS, 9P, and the overlay file system.

The packaged check script is not in PATH but can be invoked with the included xfstests-check helper.

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.

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

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.

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 user space component of CacheFiles, a caching back end that uses a directory on a locally mounted file system (such as ext4) as a cache to speed up (by reducing) access to a slower file system and make it appear more reliable.

The cached file system is often a network file system such as NFS or CIFS, but can also be a local file system like ISO 9660 on a slow optical drive.

CacheFiles itself is part of the kernel but relies on this user space cachefilesd daemon to perform maintenance tasks like culling and reaping stale nodes. Only one such daemon can be running at a time, and communicates with the kernel through the /dev/cachefiles character device.

This version modifies David Howells original cachefilesd---which appears unmaintained---to use the inotify API instead of the deprecated dnotify to monitor file changes.

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.

SiriKali is a Qt/C++ GUI application for managing encrypted folders. It supports various backends, including eCryptfs, CryFS, EncFS, gocryptfs, fscrypt, securefs, SSHFS, and Cryptomator.

bindfs is a FUSE file system for mounting a directory to another location, similar to mount --bind. It can be used for:

• Making a directory read-only.

• Making all executables non-executable.

• Sharing a directory with a list of users (or groups).

• Modifying permission bits using rules with chmod-like syntax.

• Changing the permissions with which files are created.

fscryptctl is a low-level tool written in C that handles raw keys and manages policies for Linux filesystem encryption, specifically the fscrypt kernel interface which is supported by the ext4, f2fs, UBIFS, and CephFS filesystems.

RewriteFS is a FUSE to change the name of accessed files on the fly based on any number of regular expressions. It's like the rewrite action of many Web servers, but for your file system. For example, it can help keep your home directory tidy by transparently rewriting the location of configuration files of software that doesn't follow the XDG directory specification from ~/.name to ~/.config/name.

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).

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.

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

The file command is a file type guesser, a command-line tool that tells you in words what kind of data a file contains. It does not rely on filename extensions to tell you the type of a file, but looks at the actual contents of the file. This package provides the libmagic library.

This package provides a python reference implementation for Bech32 and segwit addresses.
