Where does VLC store its config file?
Currently, a config file is created on a per user basis (there is no global configuration file). If you modify the available options in VLC and save the new configuration, then a configuration file will be created in your user directory. The precise location of this file depends on the Operating System you are running:
Linux / Unix: $(HOME)/.config/vlc/vlcrc (v0.9.0 and above), $(HOME)/.vlc/vlcrc (v0.8 and older)
Mac OS X: HOME/Library/Preferences/org.videolan.vlc HOME/Library/Preferences/VLC (v0.9 and older)
Windows 95/98/ME: C:\Windows\Application Data\vlc\vlcrc
Windows 2000/XP: C:\Documents and Settings\%username%\Application Data\vlc\vlcrc
Windows Vista/7: C:\Users\%username%\Application Data\vlc\vlcrc
(or C:\Users\%username%\AppData\Roaming\vlc\vlcrc)BeOS: config/settings/vlcrc
