Open Source Linux File Systems

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

Squashfs is a highly compressed read-only filesystem for Linux. Squashfs compresses both files, inodes and directories, and supports block sizes up to 1Mbytes for greater compression. It is implemented as a kernel module under VFS.

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.

The Ext2/Ext3/Ext4 Filesystem Utilities (e2fsprogs) contain all of the standard utilities for creating, fixing, configuring , and debugging ext2, ext3, and ext4 filesystems.

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

Open-source tool to access Amazon S3 file storage. S3cmd is a free command line tool and client for uploading, retrieving and managing data in Amazon S3 and other cloud storage service providers that use the S3 protocol, such as Google Cloud Storage. Lots of features and options have been added to s3cmd since its very first release in 2008.... we recently counted more than 60 command line options, including multipart uploads, encryption, incremental backup, s3 sync, ACL and Metadata management, S3 bucket size, bucket policies, and more!

Old home of linux NFS development; see linux-nfs.org instead now.

This project serves as a collection of different free software projects that I'm working on. The major ones are currently "HFSExplorer", "DMGExtractor", and "NTFS-3G for Mac OS X".

Extundelete is a utility to undelete files from an ext3 or ext4 partition.

The Deduplicating Warp-speed Advanced Read-only File System. A fast high compression read-only file system for Linux and Windows. DwarFS is a read-only file system with a focus on achieving very high compression ratios in particular for very redundant data. This probably doesn't sound very exciting, because if it's redundant, it should compress well. However, I found that other read-only, compressed file systems don't do a very good job at making use of this redundancy. See here for a comparison with other compressed file systems. DwarFS also doesn't compromise on speed and for my use cases, I've found it to be on par with or perform better than SquashFS. For my primary use case, DwarFS compression is an order of magnitude better than SquashFS compression, it's 6 times faster to build the file system, it's typically faster to access files on DwarFS and it uses less CPU resources.

Collectl is a light-weight performance monitoring tool capable of reporting interactively as well as logging to disk. It reports statistics on cpu, disk, infiniband, lustre, memory, network, nfs, process, quadrics, slabs and more in easy to read format.

Portable, fully-threaded I/O benchmark program

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

The Digital Forensic Tool Testing (DFTT) project creates test images for digital forensic acquisition and analysis tools. These images can be used by a tool developers and owners to test their software.

FATSort is a small utilitiy for Linux that sorts directory structures of FAT12, FAT16, FAT32 and exFAT file systems. It is written in C and can be run from the command line.

AVFS is a system, which enables all programs to look inside gzip, tar, zip, etc. files or view remote (ftp, http, dav, etc.) files, without recompiling the programs.

cramfs is a Linux filesystem designed to be simple, small, and to compress things well. It is used on a number of embedded systems and small devices.

httpfs depends on FUSE. It uses HTTP/1.1 extensions to read arbitrary bytes from a file on a web-server. This is particular interesting for an iso, since it can be investigated (loop device) without actually downloading the whole iso.

Set geometry and location parameters in NTFS filesystem, so it can boot.

BackupPC is a high-performance, enterprise-grade backup system for backing up Linux, WinXX PCs, Macs and laptops to a server's disk. Features include clever pooling of identical files, no client-side software, and a powerful Apache/CGI user interface.

Partclone is a project like the well-known backup utility "Partition Image" a.k.a partimage. Partclone provide utilities to back up used blocks and design for higher compatibility of the file system using supported library like e2fslibs.

This is a header-only single-file std::filesystem compatible helper library, based on the C++17 and C++20 specs, but implemented for C++11, C++14, C++17 or C++20 (tightly following the C++17 standard with very few documented exceptions). It is currently tested on macOS 10.12/10.14/10.15/11.6, Windows 10, Ubuntu 18.04, Ubuntu 20.04, CentOS 7, CentOS 8, FreeBSD 12, Alpine ARM/ARM64 Linux and Solaris 10 but should work on other systems too, as long as you have at least a C++11 compatible compiler. It should work with Android NDK, Emscripten and I even had reports of it being used on iOS (within sandboxing constraints) and with v1.5.6 there is experimental support for QNX. The support of Android NDK, Emscripten, QNX, and since 1.5.14 GNU/Hurd and Haiku is not backed up by automated testing but PRs and bug reports are welcome for those too and they are reported to work.

The OFF System for content storage and retrieval, lets you store all digital content and allows only the people authorized to use it to do so. It is the proof of concept for 'bright nets' and will allow anyone to securely share digital data legally.

CurlFtpFS is a filesystem for acessing ftp hosts based on FUSE and libcurl. Automatically reconnects if the server times out.

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.
