Hierarchical note-taking using dot notation in file names is a powerful method for organizing and structuring your notes. This system allows for a clear, visual representation of the relationships between different topics and subtopics. This type of note-taking was popularized by Kevin Lin and his note-taking plugin for Visual Studio Code, Dendron.
The core of this system is the use of dots (.) in file names to represent hierarchical levels. For example:
Science
Science.Physics
Science.Physics.Quantum
Main topics are represented by single words or phrases without dots:
History
Literature
Mathematics
Subtopics are created by adding a dot followed by additional text:
History.Ancient
Literature.American
Mathematics.Calculus
