Short Answer:

LuaZip is a lightweight Lua extension library used to read files stored inside zip files. The API is very similar to the standard Lua I/O library API.

Use LuaZip to read files from the archive and then write them to the filesystem using the Lua io module. If you require filesystem operations not supported by ANSI C, then take a look at LuaFileSystem. 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.
