Write the specified byte array to a file as part of an automation Workflow by using the WriteBytes component in RPA Desktop Design Studio.

## Before you begin

Role required: none

## About this task

You can configure the properties for the WriteBytes component. For more information
about these properties, see [Properties of the File components](https://www.servicenow.com/docs/yAiClLI5WYB22g9JOtBzWw "Learn about the properties of the File components in RPA Desktop Design Studio.").

## Procedure

1. In the Toolbox pane, navigate to UtilitiesFile.
2. Drag the WriteBytes component to the Design surface.
3. To configure the input fields, see [Configure port properties](https://www.servicenow.com/docs/ED3jBpqtlHH8p~yFFmyRBQ "Configure how data is passed to the input fields of a component or method in RPA Desktop Design Studio.").
4. Connect the data and control ports of the WriteBytes component to the corresponding ports of the other components as described in the following table.  
   {#use-file-writebytes__table_jnw_jn1_krb__entry__3}

   | Port type | Purpose of connection | Mandatory? |
   |-|-|-|
   | Data In (filePath) | Takes the path to the file from a previously executed component. | Yes |
   | Data In (bytes) | Takes the bytes as byte array from a previously executed component. | Yes |
   | Data Out | Returns True if the operation is successful and False if the write operation failed and passes the Boolean value to the next component. | Yes. To preview the data, right-click the Return field and click Preview Data. |
   | Control In | Connects to the Control Out port of one or more components. | Yes |
   | Control Out | Connects to the Control In port of another component or the default end component. | No. Connecting the port is optional. |
