UMX (Unreal Music Package) is a container format used by the Unreal Engine to store music tracks, typically encapsulating tracker-format audio data such as S3M, XM, IT, or MOD. It allows game music to be packaged and referenced alongside other Unreal engine assets. It is primarily used in games built on the Unreal Engine 1 and 2 for background music playback.
ICML (Adobe InCopy Markup Language) is an XML-based file format used to exchange document content and formatting between Adobe InDesign and InCopy. It preserves text, styles, and layout information so that writers and editors using InCopy can work on content linked to an InDesign layout. It is commonly used in publishing workflows for collaborative editing of page layouts.
