# File MD5 ?

This wildcard is replaced by the MD5 hash of a specified file. In case of doubt, this takes a long time and the wildcard is used in the following way:

* {file.md5.?}
* For the following input (?) --> R:\Users\Administrator\Pictures\helmut-IO.ico
* The output is going to be --> a3cca2b2aa1e3b5b3b5aad99a8529074 \[MD5 hash]

{% 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.
{% endhint %}
