Answer: The MongoDB database files are located in the MongoDB data directory, which is /data/db by default.

MongoDB stores its database files in a specific directory called the data directory. This directory contains the following files:

  • #.bson files: These files store document data. Each collection has a separate .bson file.
  • ns files: These files store information about each collection, such as the collection name, field indexes, and other metadata.
  • journal files: These files are used to record writes made to the database.
  • wiredTiger files: These files store data when using the WiredTiger storage engine.
  • config files: These files store information about the database configuration, such as replica set settings.

Modify the data directory location:

By default, MongoDB uses /data/db as the data directory, but you can pass it in Use the --dbpath option when starting MongoDB to change this location. For example:

<code class="sh">mongod --dbpath /my/custom/data/directory</code>
Copy after login
