# File Management

When the third-party jar needs to be used in the scheduling process or the user needs to customize the script, the related operations can be completed on this page. The file types that can be created include: `txt`, `log`, `sh`, `conf`, `py`, `java` etc. And you can edit, rename, download and delete files.

## Example

This sample mainly uses a simple shell script to demonstrate how to use Content Center files in a workflow definition. The same is true for tasks such as MR and Spark that require jar packages.

### Create a shell file

Create a shell file, print `hello world`.

### Create the workflow execution shell

In the workflow definition module of project Manage, create a new workflow using a shell task.

- Script: 'sh hello.sh'
- Resource: Select 'hello.sh'

> Notice: When using a resource file in the script, the file name needs to be the same as the full path of the selected resource:
> For example: if the resource path is `/resource/hello.sh`, you need to use the full path of `/resource/hello.sh` to use it in the script.

### View the results

You can view the log results of the node running in the workflow instance. As shown below:
