Hi Siva,
This can be achieved by making a workaround...
- Create file path inside the root folder
- Unpack and copy the respective files inside the root folder and repack again
- There is another option to attach files inside the Document tab. You can attach as many documents as you can, they becomes part of your job, but Not sure how about referencing those files as a part of execution... need to check
