Open Source Assembly File Systems for Windows

VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html

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.

FileSystem is an OPENSOURCE program for advanced disk management with built-in drivers for PATA IDE Hard Disks and DVD/CDROM Drives, USB Mass Storage Drivers. Implemented file systems : FAT32 / ISO9660 / EXT2. It can be compiled for DOS, LINUX, WIN32

Ranish Boot and Partitioning Tools

Operating system project from scratch to design and implement all components from boot strapping,hardware interrupts , memory manger ,file system , etc .

Perix is a 16/32/64-Bit protected mode kernel, bootable and capable of running with or without an operating system. It is written in Turbo Pascal 7.0 for DOS, Delphi 7.0, Pascal Pro, Virtual Pascal v2.1, Delphi XE2 64-Bit, TASM, TASM32 and JWASM. The latest version, 0.01I, supports multi-processor. Added Open Watcom C++ and Borland C++ examples.

The Fecundity Project has the purpose of creating a streamlined AMD64 based Operating System. We will hopefully create a stable and secure operating environment, and to investigate orthogonal persistence.

The FDOS Operaing System is 100% written in Assembler (NASM). It supports FAT 12, TSR and a small Multi Kernel System. The source is very good documentated (only in English). A German, russian and English Documentation (about 40 pages) are included.

ZoftOS is an educational operating system aimed to provide a case study on building an operating system that is similar to the *NIX and (most likely ) embedded configurations.

Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface

fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface

The Banana Kernel is an open-source pedagogical operating system intended to provide useful means for teaching basic OS concepts, with the possibility of interaction with external modules developed by the teacher or student.

BiosDiskIO is a library of Int 13h PC BIOS Disk Operations. The primary purpose is to provide quick-and-dirty access to low-level disk services, especially for file system developers and forensic analysts.

A Unix-like (Not compleatly Unix-compatible) Kernel. Right now, we have (very limited support) of 80486+ IBM-PC AT compatibles. Written in C, and assembly. No network support planned for the forseeable future.

MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler

OpenFSL is an os-independent file system library. It provides file system control with customizable disk control. Currently supports MBR and FAT32 partially.

SimplicityOS is a project designed to create a simple but powerful operating system for the pc. The kernel was designed from scrath to create a fast and stable base. The filsystem used by SimplicityOS was also designed from scratch for stability.

True kernel-level symbolic links in Windows'9x operating systems. File format is compatible with cygwin.

Provide the TINI with MultiMediaCard support, using a mixture of native and/or java classes

64-Bit journaled filesystem for Linux and Windows 2000, supporting ACLs, Named Streams, directory indexing, and Unicode.

TriOS - The Object Oriented Operating System, is the next generation operating system. Fully based on object orientation, it brings unique features to programmers and end users. Basically everything in TriOS is an object, even files and programs! Enjoy!!

The Trion Object Oriented Operating system is an OS that is designed to meet the needs for the 21st century, with a kernel written in C++ and modelled in UML, and lots of features. The project is run by a team of OSDev.org community members.

Webbsyte OS is a UNIX derivitive. We will show the learning or expert developer how to use assembly and C/C++ to create a bootable OS.

XSystem Kernel Project - an object-oriented 32-bit protected-mode operating system for IA32-architecture.
