+### smb2Client.mkdir ( path, [mode], callback )
+Asynchronous mkdir(2). No arguments other than a possible exception are given to the completion callback. mode defaults to 0777.
+
+Example:
+```javascript
+smb2Client.mkdir('path\\to\\the\\folder', function (err) {
+    if (err) throw err;
+    console.log('Folder created saved!');
+});
+```
+
 ### smb2Client.exists ( path, callback )
 Test whether or not the given path exists by checking with the file system. Then call the callback argument with either true or false. Example:
 ```javascript

lib/messages/create-folder.js

+
+
+var SMB2Message = require('../message')
+  , message = require('../tools/message')
+  ;
+
+
+module.exports = message({
+
+  generate:function(connection, params){
+
+    var buffer = new Buffer(params.path, 'ucs2');
+

+      headers:{
+        'Command':'CREATE'
