Open Source File Systems

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.

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.

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

WipeFreeSpace is a program to securely erase/wipe/overwrite/shred the free space on file systems WITHOUT DESTROYING EXISTING FILES, to prevent recovery of deleted sensitive data. This allows protecting the user's privacy when e.g. selling the drive or the whole computer. The following filesystems are supported: - Ext2/3/4, - NTFS, - XFS, - ReiserFSv3/4, - FAT12/16/32, - MinixFS1/2, - JFS, - HFS/HFS+, - OCFS. The following wiping methods are supported: Gutmann-like, random, Schneier, DoD. Additionally, WipeFreeSpace can finalize wiping the filesystem by writing blocks of zeros, which is friendly for sparse files, virtual systems and other places where zeroed-out space is not physically allocated. See the project homepage https://wipefreespace.sourceforge.io and the project Wiki in the menu above. To prevent clear-text data from being left on the drive in the first place, you can use LibSecRm (https://libsecrm.sourceforge.io), which wipes the data on-the-fly.

The Sleuth Kit is a C++ library and collection of open source file system forensics tools that allow you to, among other things, view allocated and deleted data from NTFS, FAT, FFS, EXT2, Ext3, HFS+, and ISO9660 images.

Please note that OWFS source code, and all Issue/Tickets/merge requests have now been moved to https://github.com/owfs/owfs/. Developer mailing lists will still be kept at Sourceforge. ---- OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc

SMBNetFS is a Linux/FreeBSD filesystem that allow you to use samba/microsoft network in the same manner as the network neighborhood in Microsoft Windows. Please donate me to help in SMBNetFS development.

UNFS3 is a user-space implementation of the NFSv3 server specification. It provides a unified mountd and nfsd program and so far runs under Linux, NetBSD, and Solaris.

Fpart is a tool that helps you sort file trees and pack them into bags (called "partitions"). It is developped in C and available under the BSD license. It splits a list of directories and file trees into a certain number of partitions, trying to produce partitions with the same size and number of files. It can also produce partitions with a given number of files or a limited size. Once generated, partitions are either printed as file lists to stdout (default) or to files. Those lists can then be used by third party programs. Fpart also includes a live mode, which allows it to crawl very large filesystems and produce partitions in live. Hooks are available to act on those partitions (e.g. immediatly start a transfer using rsync(1)) without having to wait for the filesystem traversal job to be finished. Used this way, fpart can be seen as a powerful data migration tool.

MooseFS (MFS) is a fault tolerant, highly performing, scaling-out, network distributed file system. It spreads data over several physical servers which are visible to the user as one resource. For standard file operations MooseFS mounted with FUSE acts as other Unix-alike file systems: * A hierarchical structure (directory tree) * Stores POSIX file attributes (permissions, last access and modification times) Supports special files (block and character devices, pipes and sockets) * Symbolic links (file names pointing to target files, not necessarily on MooseFS) and hard links (different names of files which refer to the same data on MooseFS) * Access to the file system can be limited based on IP address and/or password MooseFS on GitHub: https://github.com/moosefs/moosefs Packages repository, download: https://moosefs.com/download Documentation: https://moosefs.com/support Recent changes: https://github.com/moosefs/moosefs/blob/master/NEWS

Python FAM provides a Python module to use the File Alteration Monitor (http://oss.sgi.com/projects/fam) in Python.

MetFS is a filesystem in userspace that is FUSE based, encrypted, dynamic sized (increase when new data added, decrease when data removed), single file when it's unmounted and very fast. MetFS 's proved to be running on Linux and FreeBSD.

Network file system designed for use with home NAS. Simple to use, few dependencies, reasonable security, completely in user space.

Named Binary Tag (NBT) is a binary format designed for and used by the game Minecraft to store various data including worlds, player data and many other things. This project provides a way to access those data by simply mounting the corresponding data file as a file system, then reading and writing any value as usual file system nodes. By combining with standard Unix file operation tools, batch editing or copying massive amount of data is very easy, comparing to other generic NBT editing tools. The file system (NBTFS) implementation (mount.nbt(8)) is based on FUSE. NBT parser and writer are originally written by Lukas Niederbremer as cNBT project which this project is based on.

This library supports reading and writing Macintosh data and resource forks in AppleSingle, AppleDouble, Windows Appleshare Server, Helios, Xinet, MacLan and UShare formats.

fuse-cache is a simple caching filesystem for Linux using FUSE. It works by copying the files you want to be cached at mount time to a cache directory, , and then using that copy for all subsequent read requests for the file.

Basic Backup is a simple customizable shell script providing system admins an easy way to get basic system files backed up. Use from the moment you startup a new system and archive daily changes through bbackup. Allows you to specify which directories o

This is cryptographic disk driver for FreeBSD. It provides transparent encryption and decryption of selected devices. It is based on vn(4).

The DAFS protocol is a new file-access protocol designed to take advantage of emerging RDMA (remote direct memory access) interconnect technologies such as InfiniBand, VI and iWARP. See http://www.dafscollaborative.org/ for detailed DAFS information.

The Extensible Versioning File System, designed for Windows, Mac OS X, and Linux, introduces native versioning file system functionality to your operating system.

This project is the Fast File System. This is a mountable file system that will use a fragment of your RAM and/or Swap as a mountable device. All the files has a great performance for read/write, but all what is written will be lost at umount or reboot

The FUSE project has moved to https://github.com/libfuse/

FreeBSD Control Center is a tool that provides a graphical environment for configuration, tuning and making services available in an few clicks of the mouse.

a FUSE filesystem that allows you to store files on an IMAP account

Idas (I Don't Accept Seconds) is a high-performance duplicate file detector. Idas plugs into your favorite Unix filter and can tell you exactly which files have been seen before, regardless of whether or not it appears with the same filename.
