The file stream capability enables automation (both API Tasks and Task Bots) to handle files directly from a data source. Streaming a file directly from the data source eliminates the need to download and then upload the file from your local desktop or Control Room storage.

Overview

The file stream capability leverages the file variable to stream a file. Create a file variable and assign this variable to the file that you must stream in the Assign file to a variable option within the supported actions. Once you assign a file variable to stream a file, you can use the variable in the subsequent actions. During runtime, the automation streams the file directly from the source without the need to download and upload the file. This capability allows you to create file-based API Tasks.

The file stream is available for consumption only within the session as global values do not support file stream capability. If the session is closed, the streaming stops. Also, the actions that consume the stream depend on the source file. The file stream capability reduces the time in scenarios where you must download a file using an Assign action, and then upload it using a different action as an input for the subsequent automation.

Note:
  • If the source file is modified, the action changes accordingly.
  • If you delete the source file, the automation fails.

For example, you can use the Assign file action of Microsoft 365 OneDrive package to assign a file variable to a file available on the Microsoft 365 OneDrive location. You can use the file variable as a data source in the subsequent automation workflow. When you select the file variable as the data source, other options (Control Room file and Desktop file) are not available for selection.
