Hello,
First, V14 is an outdated release, which isn't downloadable from official sources anymore. If you really run V14, you should download the latest release, which is 2020.1.1, from 'Download' on top of this page and install it, to move to the safe side.
With 2020.1.1 and when using the default Fixed GUI, you'll find 'Local Files' as entry under 'Libraries lower left hand side, on the EDIT and the LOG tab.
