Where does Neo4j store the data?

Question

I am new to Neo4j and doing some test on Ubuntu. I was wondering where does Neo4j store the data. Where do they store the created nodes and relationships?

Answer 1

If you mean on disk, check here (for inspection purposes only of course): <neo4j_home>/data/graph.db.

Answer 2

This should help: dpkg -L neo4j
