What is a SESX file?

An SESX file contains a session created by Adobe Audition, an audio production application. It stores a multitrack audio project in an XML format, which includes mixing and effects settings. SESX files do not contain the actual audio data in a project. Instead, they save the pathnames to the audio files.
