mongodbrestore don't seem to restore all documents

In dump/enron directory messages.bson and messages.medata.json fiels. It should restore 120,477 documents. I want to restore data from it. I input command:

mongorestore -v --db enron --drop  dump/enron

After command is finished I get a messagee: 120477 objects found don't know what to do with file [dump/enron/messages.metadata.json]

But in the collection message I see 112196 documents using:

db.messages.count()

Could you please tell me what's the problem with it? The output of the command:

c:\mongodb\mongodb-win32-i386-2.0.5\bin>mongorestore -v  dump/enron/

What does the message: "don't know what to do with file [dump/enron/messages.metadata.json]" mean?

This should work:

ssharma$ mongorestore -d enron --collection messages /dump/enron/messages.bson
connected to: 127.0.0.1

You need to specify the database and the collection when restoring the bson file.

It works for me like so: 

$ mongodump -d mark --collection coll 
connected to: 127.0.0.1
DATABASE: mark   to     dump/mark
    mark.coll to dump/mark/coll.bson
         1000 objects

and

  $ mongorestore -d mark --collection newcoll dump/mark/
    connected to: 127.0.0.1
    Wed Aug 29 11:48:39 dump/mark/coll.bson
    Wed Aug 29 11:48:39      going into namespace [mark.newcoll]
    1000 objects found

Can you try - 

mongorestore -d enron --collection messages /dump/enron/
