Where are toolbar files located?

Where does LibO keep the files with toolbar definitions? Like, when i create a toolbar and choose to store it in LibreOffice Calc or LibreOffice Writer, as opposed to just my current document, where is this toolbar stored in a file?

~/.config/libreoffice/4/user/config/soffice.cfg/modules/scalc/toolbar/custom_toolbar_XXXXXXX.xml
/usr/lib/libreoffice/share/config/soffice.cfg/modules/scalc/toolbar/XXXXXXXX.xml
