Duc maintains a database of accumulated sizes of directories of the file system, and allows you to query this database with some tools, or create fancy graphs showing you where your bytes are.

Duc comes with console utilities, ncurses and X11 user interfaces and a CGI wrapper for disk usage querying and visualisation.

findimagedupes compares a list of files for visual similarity.

GNU ddrescue is a fully automated data recovery tool. It copies data from one file to another, working to rescue data in case of read errors. The program also includes a tool for manipulating its log files, which are used to recover data more efficiently by only reading the necessary blocks.

Gdu is a disk usage analyzer written in Go. It is intended primarily for SSD disks where it can fully utilize parallel processing, but it also works on HDDs.

hddtemp is a small utility that gives you the temperature of your hard drive by reading S.M.A.R.T. information (for drives that support this feature).

This package provides a library for manipulating storage volume encryption keys and storing them separately from volumes to handle forgotten passphrases.

hdparm is a command-line utility to control ATA controllers and disk drives. It can increase performance and/or reliability by careful tuning of hardware settings like power and acoustic management, DMA modes, and caching. It can also display detailed device information, or be used as a simple performance benchmarking tool.

hdparm provides a command line interface to various Linux kernel interfaces provided by the SATA/ATA/SAS libata subsystem, and the older IDE driver subsystem. Many external USB drive enclosures with SCSI-ATA Command Translation (SAT) are also supported.

udevil is a command line program that mounts and unmounts removable devices without a password, shows device info, and monitors device changes. It can also mount ISO files, NFS, SMB, FTP, SSH and WebDAV URLs, and tmpfs/ramfs filesystems.

XFE (X File Explorer) is a file manager for X. It is based on the popular but discontinued, X Win Commander. It aims to be the file manager of choice for all light thinking Unix addicts!

QDirStat is a graphical application to show where your disk space has gone and to help you to clean it up.

Wipe can erase files and block devices securely. To work properly it relies on several assumptions like having the block device write the correct sectors, etc. For files it also doesn't work on log-structured file systems such as F2FS, JFFS, LogFS, etc. You should not trust wipe to work as advertised until you have manually verified that all its assumption hold true on your system. To overwrite data it uses the Mersenne Twister pseudo-random number generator (PRNG) that is seeded with /dev/urandom or, if unavailable, /dev/random.

The dosfstools package includes the mkfs.fat and fsck.fat utilities, which respectively make and check MS-DOS FAT file systems.

lf (as in "list files") is a terminal file manager written in Go. It is heavily inspired by ranger with some missing and extra features. Some of the missing features are deliberately omitted since they are better handled by external tools.

fff (fast file-manager) is a simple, blazing fast and minimal file manager for Linux, written in bash. It only requires bash and coreutils, and its highly optimized now for efficient performance.

Sdparm reads and modifies SCSI device parameters. These devices can be SCSI disks, in which case the role of sdparm is similar to its namesake: the hdparm utility originally designed for ATA disks. However, sdparm can be used to access parameters on any device that uses a SCSI command set. Such devices include CD/DVD drives (irrespective of transport), SCSI and ATAPI tape drives, and SCSI enclosures. This utility can also send commands associated with starting and stopping the media, loading and unloading removable media and some other housekeeping functions.

GParted is a GNOME partition editor for creating, reorganizing, and deleting disk partitions. It uses libparted from the parted project to detect and manipulate partition tables. Optional file system tools permit managing file systems not included in libparted.

GNU fdisk provides a GNU version of the common disk partitioning tool fdisk. fdisk is used for the creation and manipulation of disk partition tables, and it understands a variety of different formats.

mmc-utils is a command-line tool for configuring and inspecting MMC storage devices from userspace.

ranger is a console file manager with Vi key bindings. It provides a minimalistic and nice curses interface with a view on the directory hierarchy. It ships with rifle, a file launcher that is good at automatically finding out which program to use for what file type.

Idle3-tools provides a utility to get, set, or disable the Idle3 timer present in many Western Digital hard drives. This timer is part of the "IntelliPark" feature that stops the disk when not in use. Unfortunately, the default timer setting is not well suited to Linux or other *nix systems, and can dramatically shorten the lifespan of the drive if left unchecked.

This package provides a statically-linked fsck.fat and a fsck.vfat compatibility symlink for use in an initrd.

rmlint finds space waste and other broken things on your file system and offers to remove it. rmlint can find:

• duplicate files and duplicate directories,

• non-stripped binaries (i.e. binaries with debug symbols),

• broken symbolic links,

• empty files and directories,

• files with broken user and/or group ID.

This package provides parted bindings for Python.

Duperemove is a simple tool for finding duplicated extents and submitting them for deduplication. When given a list of files it will hash their contents on a block by block basis and compare those hashes to each other, finding and categorizing blocks that match each other. When given the -d option, duperemove will submit those extents for deduplication using the Linux kernel extent-same ioctl.

Duperemove can store the hashes it computes in a hash file. If given an existing hash file, duperemove will only compute hashes for those files which have changed since the last run. Thus you can run duperemove repeatedly on your data as it changes, without having to re-checksum unchanged data.

Duperemove can also take input from the fdupes program.
