Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license with GNU LGPL + unRAR restrictions. Check the license for details.

Darik's Boot and Nuke ("DBAN") is a self-contained boot image that securely wipes hard disk drives (HDDs). DBAN is appropriate for personal use, bulk data destruction, or emergency data destruction for HDDs, but is not recommended for solid-state drives (SSDs), sanitization that requires auditable compliance documentation, or technical support.

LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

Ext2Read is an explorer like utility to explore ext2/ext3/ext4 files. It now supports LVM2 and EXT4 extents. It can be used to view and copy files and folders. It can recursively copy entire folders. It can also be used to view and copy disk and file

Create data discs with advanced data settings. Create video and audio discs, Burn will convert if needed. Create DVD-Video discs. Recreate discs. Burn doesn't reinvent the wheel, it uses many powerful open source Unix utilities and is also open source.

LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open-source software using a BSD license. This benchmark simulates simple "static content transfer" scenario such as OS Kernel compression or video game's static assets (text/images/tables/scripts/etc) which loading from Flash Memory / HDD / SSD. In this case, compression time is completely ignored. Because only content developers compress the data at once and usually they don't care about its computational cost. But they always care end user's experience a.k.a. "loading time" and bandwidth. Please pay attention to "LZ4HC -9" which is quite faster than other methods.

Please note, here you can find the latest open source release of UltraDefrag (7.1.4). The most recent UltraDefrag release (12.0.0) can be found on our official website: https://ultradefrag.net UltraDefrag is a disk defragmenter for Windows, which supports defragmentation of locked system files by running during the boot process. It is easy to use without any complicated scripting or a huge load of configuration settings. You can filter the files processed by size, number of fragments, file name and path. You can terminate the process early by specifying an execution time limit.

The FormatUsb tool is a reliable way to format USB flash drives, such as USB keys/pendrives, memory sticks,SD Memory Card, SDHC Memory Card and SDXC Memory Card SD/SDHC/SDXC Cards.

Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. Zstd can trade compression speed for stronger compression ratios. It is configurable by small increment. Decompression speed is preserved and remain roughly the same at all settings, a property shared by most LZ compression algorithms, such as zlib or lzma.

OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.

FLAC is a free lossless compressed audio format which supports streaming and archival. The FLAC project maintains the format and provides a reference encoder/decoder and input plugins for several popular audio players.

Windows XP+/32 bit native port of GNU Midnight Commander, based on the current 4.8.30 development stream. Midnight Commander (also known as mc) is a free cross-platform orthodox file manager and a clone of Norton Commander. Supports both the recent Windows 10 enhanced plus legacy consoles, 16 and 256+ colour modes are available within either. Features include the ability work with common archive formats as if they were simply another directory, and function as an SFTP/FTP client. Also includes an built-in editor/viewer, features include syntax highlighting for many languages, macros, code snippets, simple integration with external tools, automatic indentation, mouse support, clipboard and the ability to work in both ASCII and hex modes. MC can also rename groups of files, move files to a different directory at the same time as it.renames them. It lets the user specify the original and resulting file names using wildcard. https://github.com/adamyg/mcwin32

CDemu - a virtual CD/DVD drive for Linux. Project includes Linux kernel module & userspace utilities.

This is a virtual floppy drive for Windows NT / 2000 / XP / 2003 / Vista / Windows 7 (both 32-bit and 64-bit versions)

Development of this project has been moved to https://github.com/jessek/hashdeep. This site has been left for historical purposes ONLY. Please visit the GitHub site for current development. Computes the MD5, SHA-1, SHA-256, Tiger, or Whirlpool message digest for any number of files while optionally recursively digging through the directory structure. Can also match input files against lists of known hashes in a variety of formats.

Openfiler is a browser-based network storage management utility. Linux-powered, Openfiler delivers file-based Network Attached Storage (NAS) and block-based SAN in a single framework. It supports CIFS, NFS, HTTP/DAV, FTP, and iSCSI.

Lossless compressor for multichannel 8,16 and 24 bits audio data, with the ability of password data protection. Being 'lossless' means that no data/quality is lost in the compression - when uncompressed, the data will be identical to the original.

RapidCRC is a tool for windows for checking and creating CRC32 and MD5 checksums (.sfv/.md5 files). Goal is to use the fastest available (assembly) implementations for this task. Specialty: direct support for CRC32 checksums stored in filenames.

An upstream source site housing the original files for this mirror is no longer available. With this software, you can create one or more "virtual disks" on your PC/PDA. These disks operate exactly like a normal disk, with the exception that anything written to one of them is transparently, and securely, encrypted before being stored on your computer's hard drive.

Moved to GitHub.com/gdraheim/zziplib/ The ZZIPlib provides read access on ZIP-archives. The library uses only the patent-free compression-algorithms supported by Zlib. It provides functions that transparently access files being either real files or zipped files, both with the same filepath

SwiftSearch is a lightweight program whose purpose is to help you quickly find the files you need on your Windows machine without ever requiring you to index your drives. Most search utilities that achieve similar speeds do so by indexing drives while the computer is idle, but because idleness detection is so difficult to get right, in practice they end up slowing down the whole system just to speed up search. SwiftSearch works differently: given administrator privileges, it completely bypasses the file system (only NTFS supported) and reads the file table directly every time, which speeds up search by many orders of magnitude. Typically searches yield full results in ~10 seconds or less, a significant speedup for many users. As a bonus, this program also supports path-based search (for example, you can search for "*Program*\Windows*"), regular expressions (just start the search name with '>' character), and full directory sizes. Its goal is to be simple, swift, and intuitive to use.
