### Can I have different knowledge graph settings for different files in my knowledge base?
Yes, you can. Just one graph is generated per knowledge base. The smaller graphs of your files will be *combined* into one big, unified graph at the end of the graph extraction process.

### Does the knowledge graph automatically update when I remove a related file?
Nope. The knowledge graph does *not* automatically update *until* a newly uploaded graph is parsed.
### How to remove a generated knowledge graph?
To remove the generated knowledge graph, delete all related files in your knowledge base. Although the **Knowledge Graph** entry will still be visible, the graph has actually been deleted.
