It does so by scanning the directory a file is-- located in when starting playback. It sorts the directory entries-- alphabetically, and adds entries before and after the current file to-- the internal playlist. (It stops if the it would add an already existing-- playlist entry at the same position - this makes it "stable".)-- Add at most 5000 * 2 files when starting a file (before + after).MAXENTRIES = 5000
