# File Size ?

This wildcard is designed to retrieve the file size in bytes for a specified file. The wildcard is utilized in the following manner:

*  {file.size.?} 
* For the following input (?) --> R:\Users\Administrator\Pictures\helmut-IO.ico 
* The output is going to be --> 256 \[filesize in byte]

{% 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.
