**Example**

In this example, we are passing the required parameter to the function transformation object using a *Variables* object. We will be checking for an existing file.

Where,

*filePath* = *C:\Users\Kanwal.Azim\OneDrive - Astera Software\Desktop\Functions Documentation\Files\File Exists\FileExists.docx*

Right-click on the function transformation object and select *Preview Output.* As you can see, Astera Data Stack has returned the Boolean value “True”, as this file does exist.
