# File Exists ?

This wildcard is replaced by True or False, depending on whether the file that is being searched for exists or not. The wildcard is used in the following way:

* {file.exists.?} 
* For the following input (?) --> R:\Users\Administrator\Pictures\helmut-IO.ico
* The output is going to be --> True or False

{% hint style="info" %}
Ensure that the render node or server has access to file. If the the wildcard is on a server-side stream, the streams container needs to have access to the file path. Boolean return
{% endhint %}
