Deprecated since v3.2

Starting in v3.2, the $showDiskLoc operator is deprecated in mongosh. In mongosh, use cursor.showRecordId() instead.

$showDiskLoc option adds a field $diskLoc to the returned documents. The value of the added $diskLoc field is a document that contains the disk location information:

"$diskLoc": {
"file": <int>,
"offset": <int>

mongosh provides the cursor.showDiskLoc() method for $showDiskLoc:


You can also specify the $showDiskLoc option in either of the following forms:

db.collection.find( { <query> } )._addSpecial("$showDiskLoc" , true)
db.collection.find( { $query: { <query> }, $showDiskLoc: true } )
