<ul>
-<li> The main session snapshot (session_name.ardour)

-<li> Any additional snapshots (filenames ending in ardour)

-<li> the auto-backup snapshot (session_name.ardour.bak)
-</li>
-<li> the undo history for the session (session_name.history)
-</li>
-<li> the instant file (instant.xml) which records the last-used zoom scale and other metadata
-</li>
-<li> a folder called "interchange" which holds your raw audio and MIDI files (whether imported or recorded)
-</li>
-<li> a folder called "export" which contains any files created by the "Export" function
-</li>
-<li> a folder called "peaks" which contains a waveform rendering of each raw audio file in the session
-</li>
-<li> a folder called "analysis" which contains transient and pitch information of each raw audio file
-</li>
-<li> a folder called "dead sounds" which contains sounds which Ardour has detected are no longer used in the session
