Use Case:
When multiple attachments are present in a request, downloading all the attachment in a single click is more convenient than downloading one after the other.
Execution Steps:
1. Place the attachment under ..\ManageEngine\Servicedesk\integration\resources - folder.
2. Configure a Request Custom Menu: Go to Admin > Request Custom Menu > give a menu name > Action Type : Custom HTML File > downloadAll.html
3. Invoke this script from Request Details page > Actions > Menu Name.
For builds over 13000 use downloadAll_Latest.html
