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.

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.

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/

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.

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.

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

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.

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

File Tools is a convenience tool to manager different file system(based on Eclipse RCP). It supports mass rename, files/directories compare, advanced search/replace, directories synchronization, cross-platform, etc. Currently, this project is under developing, any idea is welcome.

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.

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

dracxterm is a terminal for Android. Open it and a shell is waiting. If you want a full Linux, the app can install Debian 13 or Kali inside its own storage, and you work as you would on a computer. The phone does not need root, and there is no account to create. The terminal draws colours and keeps scrollback, so full-screen programs like nano and htop look right. UTF-8 text displays properly, CJK included. You get five workspaces, each with its own shell and history, plus an extra key row for Ctrl, Alt, Esc and the arrows. Type xset to open the settings. They live inside the terminal and change as you slide them. Inside the distro, sudo, su and apt work as usual, and dpkg installs .deb packages. Every download is checked before anything is unpacked. In 1.0.6, Kali opens all the way to a prompt, and package installs on Kali Full finish. No ads and no trackers. Nothing is sent to the developer, and it goes online only when you ask for a download.
