| Option                                 | Description                                                                                                       |
| -------------------------------------- | ----------------------------------------------------------------------------------------------------------------- |
| **Include subfolders**                 | Select to copy all subdirectories in the chosen directory.                                                        |
| **Destination is a file**              | Select to specify the destination is a file.                                                                      |
| **Copy empty folders**                 | Select to copy empty directories. The **Include Subfolders** option must be selected for this option to be valid. |
| **Create destination folder**          | Select to create the specified destination directory if it does not exist.                                        |
| **Replace existing files**             | Select to overwrite duplicate files in the destination directory.                                                 |
| **Remove source files**                | Select to remove the source files after copying them. This is equivalent to a move procedure.                     |
| **Copy previous results to arguments** | Select to use previous step results as your sources and destinations.                                             |
| **Add files to result files name**     | Select to create a list of files that were copied in this step.                                                   |

If you are not using Kerberos security, this step sends the username of the logged-in user when copying the files regardless of the username entered in the connect field. To change the username, set the environment variable **HADOOP\_USER\_NAME** to the username you want to use. You can set the username by changing the **OPT** variable in the `spoon.bat` or `spoon.sh` file as shown in the following example:

```
OPT="$OPT .... -DHADOOP_USER_NAME=HadoopNameToSpoof"
```
