Your File System Is Already a Graph Database

Article Summary
The piece argues that a well-organized file system with markdown and wikilinks functions as an effective graph database for personal knowledge management, eliminating the need for specialized infrastructure.
Core Argument
The author maintains that "Files are nodes. Wikilinks are semantic edges. Folders introduce taxonomy." This simple structure, combined with LLM assistance, creates a natural language query interface to stored knowledge without requiring external databases or vector stores.
Practical Architecture
The system uses the PARA taxonomy with custom extensions:
/projects/{name}/areas/{topics}/people/{slack_handle}/daily/{year}/{month}/{day}//meetings/{year}/{month}/{day}/
The author maintains approximately 52,447 markdown files using this structure.
Key Benefits
The knowledge base serves as "a context engineering system" that improves every subsequent LLM interaction. Rather than asking an AI cold questions, users provide documented meeting notes, prior decisions, architectural context, and team discussions—yielding substantially better outputs.
Acknowledged Limitations
Automated inbox processing remains unsolved. Defining consistent processing rules while maintaining flexibility across diverse content types has proven challenging despite multiple attempts.
Getting Started
The author recommends beginning with basic folder structure, creating meeting notes linked to relevant people and projects for one week, then using the emerging graph to inform major writing projects.
