Change the extension of a path string by using the ChangeExtension component in RPA Desktop Design Studio.

## Before you begin

Role required: none

## About this task

You can configure the properties for the ChangeExtension component. For more
information about these properties, see [Properties of the File components](https://www.servicenow.com/docs/DF8Mp_LWu5HnryRAA5tlpw "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 ChangeExtension component to the Design surface.
3. To configure the input fields, see [Configure port properties](https://www.servicenow.com/docs/d92L75lHSFmmidzeOPPgTw "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 ChangeExtension component to the corresponding ports of the other components as described in the following table.  
   {#use-file-changeextn__table_jnw_jn1_krb__entry__4}

   | Port Name | Port type | Data Type | Description |
   |-|-|-|-|
   | Path | Data In | String | Takes the path to the file for which the method changes the extension from a previously executed component. |
   | Extension | Data In | String | Takes the new extension (with or without a leading period) that the method changes from a previously executed component. Specify null to remove an existing extension from path. |
   | Return | Data Out | String | Returns the changed extension value in string format. |
