+#### fs.mkdtemp(prefix, options, callback)<a name="mkdtemp"></a>
+
+
+Makes a temporary directory with prefix supplied in `path` argument. Method will append the six randomly selected characters directly to the prefix.
+
+Asynchronous. Callback gets `(error, path)`, where path is a path to created directory.
+
+NOTE: Filer allows for, but ignores the optional `options` argument used in node.js.
+
+Example:
+
+```javascript
+// Create tmp directory with prefix foo
+fs.mkdtemp("foo-", function (error, path) {
+    //A new folder foo-xxxxxx will be created. Path contains a path to created folder.    
+});
+
+fs.mkdtemp("/myDir/tmp", function (error, path) {
+    //Will create a new folder tmpxxxxxx inside myDir directory. 
+    //Will throw error if myDir does not exist    
+});
+
+```
+
 #### fs.readdir(path, callback)<a name="readdir"></a>
 
 Reads the contents of a directory. Asynchronous [readdir(3)](http://pubs.opengroup.org/onlinepubs/009695399/functions/readdir.html).
