XLTX at a glance

XLTX

XLTX followed the same OOXML-era pattern as DOTX: preserve the template workflow, but place it inside the newer package-based office family.

M4P at a glance

M4P

M4P belongs to the iTunes-store period when downloadable music was widespread but still strongly shaped by platform-controlled authorization and protection systems.
