[DirectoryTree]When you are using name as an "id" you will get an error when the same name occurs again for example 

For example when we will have inside our folder 
**_a_** with folder **_c_** with folder **_d_**
and
**_b_** with folder **_c_** with folder **_e_**
the output will be 

```
a
-c
--d
b
-c
--d
```
but should be  

```
a
-c
--d
b
-c
--e
```
