Yes, if you don't need any of your data, just delete the files there. It will remove all the data, indexes and metadata.

If you are running in a replica set, you can do this too and it will automatically download all the data from one of the other healthy nodes which is really cool!

var dbs = db.getMongo().getDBNames()
for(var i in dbs){
    db = db.getMongo().getDB( dbs[i] );
    print( "dropping db " + db.getName() );
    db.dropDatabase();
}

save it to dropall.js and then execute:

mongo dropall.js
