TheRead Text File component reads and outputs the contents of a file as plain text.
To add it to a flow within the Flow Designer, go to the Toolbox panel, expand the category Integration > File and then, drag a Read Text File component to the workspace.

Example

This example begins with the assumption that our file system contains a text file called Sample Text File .
The example flow will read this file and display its content inside of a form field. The form, Read Simple Text File , already exists, and is simply configured with a Text Box Multi Line form control, label, and a button:

The first step in our flow will be the Read Text File component.

In theFlow Designer Quick Add window, go to Integrations > All Integrations > File , select a Read Text File component. Click Add to add it to the workspace.

The next step in our flow will be the form we use to display our file contents -Display Sample Text File Form - which is in theToolbox panel, under the categoryForms [Interaction] > [Current Folder] .

Next, configure Read Text File by selecting it and clicking the Edit Input Mappings link on theActions Toolbar .
Our example flow requires thatRead Text File should read the file C:\SampleTextFile.txt , so give the input file Name a mapping type of Constant and a value of the path and file name. With that done, we can clickOK to close the Mapping Editor .

Our example flow requires thatDisplay Sample Text File Form should display the file contents provided by Read Text File step**.** Therefore we will map the output ReadTextFile_Output to our form's input FileData. Click OK to close the Mapping Editor. Click the Debug Flow link to test the flow.

In the debugger, we're presented with a form with one field containing data from our text file.
