| .png) **Example** In this example, we are passing the required parameters to the function transformation object using a *Variables* object. We will be copying a “Test.txt” source file to a different destination file folder. Where, *sourceFilePath* = *C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Files\AppendTextToFile\Test.txt* *destFilePath* = C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Files\CopyFile\Test3.txt *overWrite* = False .png) Right-click on the function transformation object and select *Preview Output.* While the *Data Preview* will not generate an output. Upon opening destination file location, you can see that Astera Data Stack has copied the Test.txt file, with the specified name, Test3.txt. .png)
