WinFSP is a framework for implementing custom file systems on Windows. It enables the creation of user-mode file systems that appear as standard disk drives or network shares to the operating system, allowing developers to implement file system logic in user space via a proxy architecture that avoids the need for custom kernel code. A primary differentiator is its FUSE compatibility layer, which maps POSIX-based file system calls to native Windows requests. This allows existing file systems written for the FUSE API to be ported to Windows and Cygwin environments. The project covers a wide ra

This is an open-source, crowd-sourced wiki textbook that teaches Linux system programming in C. It covers the core operating system concepts of process management through the fork-exec-wait model, dynamic memory allocation using implicit free list heap allocators, inode-based file systems, inter-process communication via pipes and shared memory, POSIX threads with synchronization primitives, signal-based asynchronous notification, virtual memory with page table translation, and runtime diagnostics using Valgrind and GDB. The textbook distinguishes itself by providing practical, implementation

mergerfs is a FUSE-based union filesystem that pools multiple independent filesystems or directories into a single unified mount point. It acts as a proxy to underlying storage, forwarding file operations directly to the filesystem for near-native performance while merging directory listings and attribute changes. The project provides a live, read-write pooled view of storage that aggregates drives of any size without requiring reformatting or data redistribution, and it isolates individual drive failures so that the pool continues serving data from remaining filesystems. The filesystem offer

Goofys est une passerelle de stockage objet cloud compatible POSIX qui présente des buckets de stockage distants comme des répertoires système locaux. Il implémente un système de fichiers en espace utilisateur (user-space) qui mappe les services de stockage S3 et Azure Blob vers des points de montage locaux, permettant d'accéder aux objets distants via des opérations système standard. Le projet offre des capacités de montage spécifiques pour les comptes Amazon S3, Azure Blob Storage et Azure Data Lake. Il utilise une implémentation basée sur FUSE pour interfacer le stockage objet cloud avec le noyau du système d'exploitation. Le système inclut des optimisations de performance telles que la mise en cache locale en lecture pour réduire la latence et la récupération concurrente par plages (range-request) pour optimiser le téléchargement de gros objets. Il simule des structures de dossiers hiérarchiques en analysant les préfixes des clés d'objets pour émuler des répertoires.
