+
+To rename all revisions of a stored file with the specified filename, drivers SHOULD provide the method
+`delete_by_name`:
+
+```javascript
+class GridFSBucket {
+
+  /**
+   * Deletes all stored files with the specified @filename from a GridFS bucket.
+   */
+  void delete_by_name(string filename);
+
+}

+
+This method is an optimisation over deleting each revision of a stored file individually.
+
+**Implementation details:**
+
+Drivers MUST first find the `_id` field of all files collection documents with the given filename. Drivers MUST then
+delete all chunks with `files_id` in the found ids that was just deleted. Drivers MUST then delete all files collection
+documents with the found ids.
+
+If there are no files collection documents with the given filename, drivers MUST raise an error.
