The Multiple File Upload/Download control allows end-users to upload or download multiple files at runtime. The inputs received from the Form control can be mapped in a Flow by defining the data as FileData or a File References datatype. When a document is uploaded into Decisions through a Flow, there is no native scan to ensure that the file uploaded is not malicious. To help ensure Decisions is secure, certain file types can be excluded.
Configuration
- In a Designer Project, create a Flow.
- In the Toolbox panel, attach a Show Form step to the Start step. On the Properties panel, click PICK OR CREATE FORM and create a Form.
- Configure the Form with a Button (Submit) and a Multiple File Upload control (files). On the Properties panel, change the OutputType field to FileReference.
- Click Save and close the Form Designer, then Debug the Flow. Pass in example files, any files passed in will have their name outputted from the step.
