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.

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

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.

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.

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.

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.

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

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.

Text and binary file transformation. Text-based sed, awk, etc. failed me when I needed a simple way to transform binary files to something else. Transformenator is what resulted.

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

Using this small tool, you could actually fake a file size to any limit, keeping the file uncurropted and usable just as it in normal form. In Short - It Increases the size without damaging the file. Warning: If you try to 'decrease' the file size, you may lose the contents of the file but this is NOT the case while increasing the file size

A simple utility to split a concatenated vCard format file into separate files (IETF RFC 2426 - vCard MIME Directory Profile). It splits on the BEGIN:VCARD and END:VCARD tags. It was created to help import a Lotus Organizer export file into Palm Desktop

Rename files with advanced capacity (recursion, undo, regular expression, variables...) for Windows and LINUX. Comments and Help welcome. You must install JAVA Runtime V1.6 or more. See http://jfrenamer.sourceforge.net/

jc means Java Commander - it's a java-based file manager for Windows and Linux

A GUI Java utility to split a file into multiple chunks. A typical application is to copy a large file onto several floppies. It generates MD5 for each chunk.

A similar to Tripwire, file system integrity checking tool but develop in java and cross platform. This tools checking and source control using check sum algorithm like MD5, SHA and CRC.

Transliterator between any Language files - Map Fonts, Create Encoding Scheme, Input Phonetic, Indian, Roman, Tamil, Hindi, English, French, German, Spanish or Any World Language Keyboard. Ex: [Phonetic Input]-[Any World Language Output] or ViceVersa.

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.

Fisy is a simple and lightweight application dedicated to copy and backup files. This application has been designed to perform simple or timestamped copies of directories and files as well as unidirectional synchronization of file tree. Fisy is in command line, you can so start copying tasks at any time or plug them on an automated processing. Sine version 2.0, Fisy contains cipher features for encrypting data for storage in a remote service like the Cloud.

J2MEFS is an API for the J2ME that extends the RMS. It lets you save persistent data in your MIDlets without even knowing what a RecordStore is. You can create a structure of directories and access files through names and paths (MIDP 1.0 and above).

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.

The project Jaulp is jet another utility library project written in Java. It contains utility classes for Date ,Calendar, Collections, Resources, Files, IO for Random data, and many more. This is the last version for this project.

Java Virtual System (JVS) is built around a virtual file system (VFS) - a common platform of Java, by Java, for Java. JVS extends JVM and makes it from an interpreter running half-compiled code a first-class server.
