Are any parts related to specifically WindFind open-source?

Are the file/directory indexing parts of this project open-source? I have looked in the WindTerm repository, but haven't found source code related to this.

The filesystem indexing speed of this project as a regular user is quiet impressive.
The same with the db/struct storage size of the project.

Kind regards

Start by reviewing the WindTerm repository and this project's source tree for the file and directory indexing or db/struct storage components mentioned in the issue. The work would be complete when the relevant source locations are identified and the project's open-source status for those parts is clearly documented or answered.

Written by the indexing model from the issue text.
