Answer / Deep Kumar
When you delete a document from MongoDB, the document is marked as deleted and moved to a special collection named `.trash`. The space occupied by the deleted document is not immediately reclaimed. However, the deleted document remains on disk until garbage collection runs, which helps ensure data integrity and recoverability. In some configurations, you can also set up tiered storage or change journaling options to optimize for disk usage.
