Documentation about the LyX system directory
The system directory (a.k.a. Library Directory) holds global settings and files used by LyX. If you want to tweak those, you should do this in the user directory (unless you are a system administrator).
The location of the LyX system directory depends on how LyX has been installed. Here are some common possibilities:
- Linux and other Unix-like systems:
/usr/local/share/lyx/ or /usr/share/lyx/
- Windows:
C:\Program Files\LyX<VERSION>\Resources\
- Mac OS X:
Lyx.app -> show package -> Contents/Library
The Help→About LyX dialog contains information about where your system directory (Library Directory) is:
The system directory should contain the following subdirectories:
bind/- standard keybinding files (keyboard shortcuts)
clipart/- stock graphics used in the documentation
commands- configuration file for the "call" lyx function (cf. this explanation)
doc/- the LyX manuals
examples/- example documents for various text classes
fonts- fonts needed by LyX (e.g. to display math)
images/- icons and other images needed by the User Interface

scripts/- various (python) helper scripts used by LyX
templates/- template files (accessed with File→New from Template)
tex/- tex classes and styles shipped with LyX (in order to be detected by LaTeX, these files must be copied to the TEXMF directory).
