1-Wire File Structure

Abstract: This application note discusses the 1-Wire® File Structure (OWFS). The OWFS provides a directory structure for data residing in 1-Wire devices including iButtons. It allows named files to be randomly accessed as they are on other file systems. This document provides the full specification including bitmap files for large capacity 1-Wire devices, multiple subdirectories, extended file attributes, and other useful constructs such as files spanning multiple devices.
