# Path Basename ?

This wildcard is replaced with the filename of a path (without extension). Any path can serve as input. The wildcard is used in the following way: 

* {path.basename.?}
* For the following input (?) --> c:\Users\Administrator\Pictures\helmut-IO.ico
* The output is going to be --> helmut-IO

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