The filemd5 command returns the md5 hashes for a single files stored using the GridFS specification. Client libraries use this command to verify that files are correctly written to MongoDB. The command takes the files_id of the file in question and the name of the GridFS root collection as arguments. For example:
{ filemd5: ObjectId("4f1f10e37671b50e4ecd2776"), root: "fs" }
