  2. Select all symbols (not the directory!), right click and sent to compressed (zipped) folder.
    All symbols should be in the root of the zip file, a symbol library will not list symbols that are placed in a sub folders.
  3. Change the file extension from .zip to .osl
  4. Copy the .osl file to the Orbit symbols directory : <Orbit installation directory>/program/symbols
  5. Restart Orbit
