Free filesystem driver software for linux

ASFS is a filesystem driver for the Linux kernel that adds support for the Amiga SmartFileSystem. ASFS filesystem driver supports both read and write, however, write support is in an early beta stage.
ASFS - Amiga Smart File System - Linux implementation
Version 1.0beta8 in "read-only mode" should be considered as the lasted stable version of ASFS driver.
It is available for Linux kernel version 2.6.x.
From version 1.0 there is also full write support. Use it with care. It is in EXPERIMETAL stage and COULD be DANGEROUS.
Remember! YOU USE THIS DRIVER AT YOUR OWN RISK. Read included docs for
more details.
Enhancements:
- The code was updated to match changes in the VFS of Linux kernel 2.6.19.

SSH Filesystem is a filesystem client based on the SSH File Transfer Protocol. Since most SSH servers already support this protocol it is very easy to set up: i.e. on the server side theres nothing to do. On the client side mounting the filesystem is as easy as logging into the server with ssh.
The idea of sshfs was taken from the SSHFS filesystem distributed with LUFS, which I found very useful. There were some limitations of that codebase, so I rewrote it.
Main features:
- Based on FUSE (the best userspace filesystem framework for linux ;-)
- Multithreading: more than one request can be on its way to the server
- Allowing large reads (max 64k)
- Caching directory contents
Installing
First you need to download FUSE 2.2 or later from http://fuse.sourceforge.net/. You also need to install the devel package for glib2.0. After installing FUSE, compile sshfs the usual way:
./configure
make
make install (as root)
How to mount a filesystem
Once sshfs is installed (see next section) running it is very simple:
sshfs hostname: /mountpoint
Note, that its recommended to run it as user, not as root. For this to work the mountpoint must be owned by the user. If the username is different on the host you are connecting to, then use the "username@host:" form. If you need to enter a password sshfs will ask for it (actually it just runs ssh which ask for the password if needed). You can also specify a directory after the ":". The default is the home directory.
Enhancements:
- This release fixes a couple of rarely occurring crashes and some smaller bugs.

FileSystemStorage is a project that provides FileSystem storage for Archetypes.

FileSystemStorage is an Archetype storage for storing data on FileSystem This storage is used to avoid ZODB to grow quickly when using a lot of large files.

FUR is a application that let the user mount a Windows CE based device on your Linux file system: it uses the brilliant FUSE (acronym of File system in UserSpacE of Miklos Szeredi) and the great librapi2 of the Synce Project, a unix implementation of the RAPI protocol (that your device use to communicate with your other operating $ystem ) which you can find here, along with other very nice tools.
You execute it with proper arguments, then (if everything goes fine) the entire file system of your (previously connected) handheld will appear automagically mounted like a regular Linux file system where you will be able to copy, move read and write data with your favorite programs.
FUR filesystem means FUSE use libRAPI.
What dose not?
- Not very stable, particulary if used concurrently by different processes (but should be usable).
- Not well tested.
- The source is horrible(Tm).
- The implementation is more involved than it should.
- Lack documentation.
- Not even remotely optimized.
- Configuration tools deficient.
- Random access I/O is anti-optimized.
- Write is bugged (maybe a problem with concurrent file access).
- The resource locking system (e.g. to prevent different processes to write on the same file) is only roughly implemented (theres a lot to be done).
- Total absence of a caching system of some sort (which i hope to implement, sooner or later).
- Some errors are to obscure (and maybe not well implemented).
- Some attributes (e.g. ctime) are not implemented (the needed function in the librapi2 library is not yet implemented).
- No UID/GID check: this is not a security issue: only the user that invoke the dccm demon can access the filesystem, but other users should be able to see some kind of error message (which i will implement soon).
- Lot of other things i have forgot now.
- The log reporting suck

MP3::Find::Filesystem is a File::Find-based backend to MP3::Find.

SYNOPSIS

use MP3::Find::Filesystem;
my $finder = MP3::Find::Filesystem->new;

my @mp3s = $finder->find_mp3s(
dir => /home/peter/music,
query => {
artist => ilyaimy,
album => myxomatosis,
},
ignore_case => 1,
);

The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware.
It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
Main features:
- Efficient support for all types of audio interfaces, from consumer soundcards to professional multichannel audio interfaces.
- Fully modularized sound drivers.
- SMP and thread-safe design.
- User space library (alsa-lib) to simplify application programming and provide higher level functionality.
- Support for the older OSS API, providing binary compatibility for most OSS programs.

Intelligent Filesystem Guard is a tool that monitors information about changes in files and directories.

Intelligent Filesystem Guard can be used either for the detection of changes in important files (as an intrusion detection system guarding data against viruses and Trojan horses) or for guarding user data.

A large emphasis is put on monitoring files. One of the functions of this system is to tell what happened with the file according to a user query. The system is able to warn of any sort of change, such as modification, creation, erasure, or movement.

HDBC Sqlite3 Driver is the Haskell Sqlite v3 backend driver for HDBC.

Please see HDBC itself for documentation on use. If you dont already
have it, you can browse this documentation at
http://darcs.complete.org/hdbc/doc/index.html.

This package provides one function in module Database.HDBC.Sqlite3:

{- | Connect to an Sqlite version 3 database. The only parameter needed is
the filename of the database to connect to.

All database accessor functions are provided in the main HDBC module. -}
connectSqlite3 :: FilePath -> IO Connection
