  '''Why Does This Page Exist?
+
The directories are listed in alphabetical order, with an overview of their contents on the right. Any first level subdirectories are shown as well.
−
  Well, simply because VLC has evolved with not so much accumulation in mind,

−
  and when a new coder looks at the code, s/he is  terrified by the abundance of directories.
+
For detailed documentation on VLC modules, please see '''[[Documentation:Modules]]'''.

  Please remove this paragraph when done.'''

'''''Note:''''' This table is by no means exhaustive. Note that only plugins with their own subdirectories are listed; plugins inside the parent directories are not emphasized unless they are too important. For a comprehensive list of the plugins VLC makes use of, consult {{VLCSourceFile|modules/MODULES_LIST}} in your source code checkout.
