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.

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.

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.

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

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

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.

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

This software finds duplicate files across all directory levels inside a given folder.

A very simple, but useful, application that creates a list of files in any folder/directory on your computer.

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.

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.

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.

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

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.

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

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.

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.
