https://community.appian.com/discussions/f/general/6524/i-need-to-generate-a-text-file-and-then-update-the-extension-to-something-elseI need to generate a text file and then update the extension to something else (a special extension) before I copy it to a file system. Is there a way to accomplish this without creating a custom function/smart service?

For some reason I didn&#39;t think that smart service would accept a template with a non .txt extension.

We need custom smart service to do this. Changing an extension is nothing but changing the file type. For this, you need to build a custom expression to achieve this activity.<div style="clear:both;"></div>
