+GridFS is a convention drivers use to store and retrieve BSON binary data (type "x05") that exceeds MongoDB's
 BSON-document size limit of 16 MiB. When this data, called a **user file**, is written to the system, GridFS divides the
 file into **chunks** that are stored as distinct documents in a **chunks collection**. To retrieve a stored file, GridFS
 locates and returns all of its component chunks. Internally, GridFS creates a **files collection document** for each

 **Implementation details:**

 of being deleted, drivers MUST first delete the files collection document for a stored file, then delete its associated
 chunks.
