# File Content ?

This wildcard is replaced by the content of a defined text-based document. The wildcard is used in the following way: 

* {file.content.?} 
* For the following input (?) --> c:\values.txt
* The output, for example, is going to be --> a,b,c,d

{% hint style="warning" %}
Please ensure that the path intended for use within the wildcard has already been resolved to a valid UNIX or UNC path. Note that a mapper node cannot be utilized within the wildcard.
{% endhint %}

For example {file.content./Volumes/helmut/file.txt) or {file.content.\\\helmut\file.txt}

**Invalid**: {file.content.{path.map.to.unix.H:\helmut}/file.txt)

{% hint style="info" %}
Ensure that the render node or server has access to file. If the wildcard is used on a server-side stream, the streams container needs to have access to the file path Streams engine needs to be able to read the file content. Use this functional wildcard to read text-based documents.
{% endhint %}
