Ansys Lumerical product preference files

Overview

Ansys Lumerical product configuration is stored in a series of "preference" or configuration ".ini" files. These ".ini" files are stored in a hidden folder in your "home" directory. 

• License.ini: Contains the license server information.
• Launcher.ini: Stores Launcher-specific (GUI) settings.
• Shared.ini: Shared settings for all products/solvers. Including recently opened files, scripts, and application examples.
