Folder Size ?
This wildcard is replaced by the total size of all files of the specified folder. The wildcard is used in the following way:
{folder.size.?}
For the following input (?) --> R:\Users\Administrator\Pictures [Folder Path]
The output is going to be --> 18521
Ensure that the render node or server has access to the folder path . If the wildcard is on a server-side stream, the streams container needs to have access to the folder path.
