## Overview

LuaFileSystem is a Lua library developed to complement the set of functions related to file systems offered by the standard Lua distribution.

LuaFileSystem offers a portable way to access the underlying directory structure and file attributes.

LuaFileSystem is free software and uses the same license as Lua 5.x (MIT).

Current version is 1.7.0. It works with Lua 5.1, 5.2 and 5.3, and it runs on various flavors of Unix (including Linux, BSDs, macOS) and Windows.

## Download

LuaFileSystem can be installed using LuaRocks:
