File
File is a command-line utility and C library designed to determine the precise file format and media type of unknown files by inspecting their internal byte sequences, binary signatures, and hierarchical pattern rules rather than relying on file extensions. The software evaluates magic number signature matching and complex multi-byte offsets to classify files accurately.
The engine supports recursive archive inspection, automatically unpacking compressed archive structures on the fly to analyze and identify internal nested file payloads. Human-readable pattern definitions can be compiled into an optimized binary format for rapid runtime traversal.
Through its in-process shared library architecture, the project exposes native classification routines directly to custom software applications via a C-compatible function interface, enabling programmatic file inspection without spawning external processes.
