AXF can encapsulate any type of file and supports interoperability among different content storage systems. SMPTE Working Group on AXF chairman S Merrill Weiss said: “By abstracting the underlying technology of digital storage, AXF not only supports interoperability among today’s discrete storage systems, regardless of the operating and file systems used, but also future proofs digital storage so that content remains available despite changing formats and storage technologies.”
