PhysicsFS (PhysFS for short) is a zlib-licensed programming library written in C for virtual file access. PhysicsFS is designed to provide a hardware abstraction layer to the developer, allowing them to access files contained within various archive formats as well as direct access to the filesystem, which would all be represented in a single virtual Unix-like file tree. PhysicsFS initially supported ZIP, Quake PAK, and Doom WAD file formats, but recent editions expand filetype support to 7z, Build engine GRP, and Descent HOG and MVL formats.
PhysicsFS is mainly used in the video game industry, but can be used by other sorts of programs, too. The Allegro, LÖVE and NAS2D game engines support it natively. Video games that use PhysicsFS include Dead Meat, netPanzer, and MindBender.
