Open Source Java File Systems

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".

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.

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.

This simple tool allows you to change the extensions of files in a given directory (and subdirectories) from one type to another. No fluff or overblown GUI; does what it says on the tin.

droiD64 is a graphical filemanager for D64 files (Commodore 64 and others). May this tool make life easier for Commodore 64 fans, especially for those using MAC and Linux systems as there are tools available for Windows anyway.

A Java library that allow Java applications to receive file system events on Windows and Linux.

Davenport is a servlet-based WebDAV gateway to a CIFS network. This allows you to access Windows/Samba shares using any web browser. WebDAV clients (such as Windows Web Folders) can upload and download from the shares as if they were local folders.

DirSize is a directory reporting tool. It recursively scans the provided (or current) directory, and reports the number of files and director sizes of each subdirectory present. It also defaults to sorting by by directory size, but there are other options. One of the interesting things about DirSize is it shows a visual representation of the file sizes of counts. I call this a SizeMap or FilesMap and it's the area to the right of the output. If you sort by size (default or -ss) or directories (-sd) is will show the SizeMap. If sorted by file counts (-sf) the map will change to show a visual representation of the number of files per subdirectory, sorted from high to low. This is a single executable JAR file. While you will need Java installed, there is no need to install this program. Just download the JAR file, please it somewhere convenient, and execute it from the command line: java -jar dirsize.jar See https://github.com/frossm/dirsize for details

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

IngestList is a java based tool to perform automated batch identification of file formats and to characterise some important properties. It is designed to meet the fundamental requirement of any digital repository.

DigiExtractor is a tool to allow extraction of video recordings from the DigiCorder series of DVB receivers manufactured by TechniSat.

A file watching facility for Java. Uses native platform support to avoid polling on selected platforms (currently supports win32, Mac OS X, Linux and FreeBSD on x86 platforms). Implements JDK 7's WatchService, but also runs on Java 5 and 6

Hash is fast and simple java utility program for calculating and verifying checksums for files and text. Hash can generate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksum values.

File Master is created to assist you when handling many files at one time. File Master can for example rename many files at once, or zip them for storage.

Apache Commons VFS utilities such as a bridge to the Apache Mina FTP Server, a bridge to the Apache Mina SSHD / SCP / SFTP server and a scriptable Java Shell / Console providing a Command Line Interface with VFS file system commands and operations.

JFileSync is a Java application used to synchronize directories of two different file systems. For instance, you want to synchronize a set of directories on your laptop with a set of corresponding directories on your workstation.

The “Media Crawler” is an extensible Eclipse RCP based desktop application which will crawl a given file system, extract metadata from files, map metadata to internal schemas and store the metadata in a databse. This project is ANDS-funded.

This FUSE based file system allows you to browse the Apple Trailers page like a directory structure on your computer. appletrailerfs will be optimized for use with the Western Digital TV HD but does work with any OS supported by FUSE.

Commons VFS is a standarised VFS layer for Java, developed by the Apache project. Commons VFS Grid is a collection of file system providers for Commons VFS, which provide SRB, GridFTP and other Grid file systems.

dupliFinder is a app that searches your computer for duplicate files by compairing the MD5 sum of each file. You then have the option of deleting any duplicate files found. Great for collections of MP3s, images etc.. Runs on Windows & Linux with Java 1.5

Uniqueoid program is designed for searching and deleting copies of files. Uniqueoid analyses target files and folders and offer to save one of the duplicates and eliminate the else. Search results can be saved and loaded. You may clean disk bit by bit. Uniqueoid takes care of files that become unique even after the end of the search. Unique files can’t be deleted accidently. Also Uniqueoid can automatically choose or ignore files by directory or path prefix. All this features in combine allows to reduce such routine and boring task as a getting rid of repetitive fotos, documents, music tracks and so on to some easy actions, no matter how much copies are involved. Uniqueoid is as simple as possible. It doesn’t require special knowledge in the computer architecture. At the same time program has extended settings for optimization for custom system and preferences. Uniqueoid is written in Java. It can be run on any OS where actual JRE is installed. Uniqueoid is a free software.

FileRally is a launcher or dock for files. FileRally displays an always up-to-date virtual folder containing your most frequently used and most recently used files. The files you are most likely to need are at your fingertips without navigation, without searching, without settings changes, and without an app launcher. Setup is extremely simple. Just point to your files and go. See settings screen shots below and project web site. v1.4 is for 64-bit systems only. Use v1.2 with 32-bit systems.

JSP Based File Manager. Allow view, create, edit, copy, move, delete, rename, compress/uncompress of directories and text type files. Allow transposition and resizing of image type files. Also allow external viewers and editors to be invoked for files.

N-way Folder Diff is a simple, platform independent tool to compare multiple folders. It differs from usual diff tools because it is possible to do n-way (upto 10 way) diff as compared to the usual 2-way diff.

Java Batch Job Framework. The JBJF uses an XML definition file to abstract many of your common batch job parameters. The JBJF programming framework uses a task list concept as a divide and conquer strategy to simplify your batch job development.
