	<brief_description>
		Allows reading the content of a ZIP file.
	</brief_description>
	<description>
		This class implements a reader that can extract the content of individual files inside a ZIP archive. See also [ZIPPacker].
		[codeblock]
		# Read a single file from a ZIP archive.
		func read_zip_file():
		    var reader = ZIPReader.new()
		    var err = reader.open("user://archive.zip")
		    if err != OK:
		        return PackedByteArray()
		    var res = reader.read_file("hello.txt")
		    reader.close()
		    return res

		# Extract all files from a ZIP archive, preserving the directories within.
		# This acts like the "Extract all" functionality from most archive managers.
		func extract_all_from_zip():
		    var reader = ZIPReader.new()
		    reader.open("res://archive.zip")

		    # Destination directory for the extracted files (this folder must exist before extraction).
		    # Not all ZIP archives put everything in a single root folder,
		    # which means several files/folders may be created in `root_dir` after extraction.
		    var root_dir = DirAccess.open("user://")

		    var files = reader.get_files()
		    for file_path in files:
		        # If the current entry is a directory.
		        if file_path.ends_with("/"):
		            root_dir.make_dir_recursive(file_path)
		            continue

		        # Write file contents, creating folders automatically when needed.
		        # Not all ZIP archives are strictly ordered, so we need to do this in case
		        # the file entry comes before the folder entry.
		        root_dir.make_dir_recursive(root_dir.get_current_dir().path_join(file_path).get_base_dir())
		        var file = FileAccess.open(root_dir.get_current_dir().path_join(file_path), FileAccess.WRITE)
		        var buffer = reader.read_file(file_path)
		        file.store_buffer(buffer)
