+<h3>Regions Are Not Files</h3>
+<p>
+ Although a region can represent an entire audio file, they are never
+ equivalent to an audio file. Most regions represent just parts of an audio
+ file(s) on disk, and removing a region from a track has nothing to do with
+ removing the audio file(s) from the disk (the <kbd
+ class="menu">Destroy</kbd> operation, one of Ardour's few destructive
+ operations, can affect this). Changing the length of a region has no effect
+ on the audio file(s) on disk. Splitting and copying regions does not alter
+ the audio file in anyway, nor does it create new audio files (only
+ <dfn>recording</dfn>,
+ and the <kbd class="menu">Export</kbd>, <kbd class="menu">Bounce</kbd> and
+ <kbd class="menu">Reverse</kbd> operations create new audio files).</p>
