## What it is
LuaFileSystem is a C-based Lua library that complements the standard Lua distribution's file system functions. It provides a portable way to access directory structures and file attributes across Unix flavors and Windows.

## Use cases
- list directory contents in Lua
- get file attributes like size and modification time
- create and remove directories portably
- work with symbolic links in Lua
- get the current working directory
- lock files for concurrent access

## When to choose
- you need portable file system access in Lua across Unix and Windows
- you need file attributes, symlinks, or directory iteration beyond Lua's standard io library
- you want a mature, MIT-licensed library supporting Lua 5.1 through 5.5

## When to avoid
- you only need basic file reading/writing, which Lua's standard io library already covers
- you need async or high-performance file I/O
- you are not working in Lua

## Facets
- artifact type: library
- maturity: stable
- function: file-system
- domain: developer-tools, files, cross-platform
- platform: windows, bsd, lua
- tags: lua, luarocks, directory-structure, file-attributes, portable, linux, macos, android
