In RAD Studio what is the a file that contains the Delphi library paths?

In RAD Studio version 12.1 under the Tools -> Options -> Language -> Delphi -> Library there is a text box labeled Library Path. If I click the button to the right of the textbox it opens a popup with a list of paths that can be added or removed.

Is there a file in Delphi that holds that information and can that file be updated externally?

I have a lot of paths that I need to add and it would be much easier to copy them into a file rather than selecting the path, and clicking add for each one.

I couldn't find anything about this on the Embarcadero website. I looked to see if there were any files that had a name that sounded like it might hold this kind of data but could not find anything.

I just want to know if it is possible and what file

The information is in a the

c:\Users\username\AppData\Roaming\Embarcadero\BDS\23.0\EnvOptions.proj

file but that file is updated by the values in the Registry. If you make any changes to the EnvOptions.proj file they will be lost.

In RegEdit navigate to: Computer\HKEY_CURRENT_USER\Software\Embarcadero\BDS\23.0\Library\

Depending on which Operating System you want to use these paths (in my case it is Win32) then append that Operating System path to the end of the above path.

In the keys for that path go to Search Path and right click and then click Modify. All of the paths are stored in the Value Data string. You can add or remove them from this string. Each path terminates with a semi-colon ;. There are no carriage returns or line feeds or any other special characters. It is all one long string separated by semi-colons.

The order the path is in that string is the order it is displayed in this list:
