String Manipulation

Hi,

I am really struggling with knime’s functionality to extract parts of a string. I have attached some images

I would like to extract 2 parts from this string: Q:\Strategy Deployment\B100+ Tableau Files\1 - Data Store\2025\Brand\test initiative.xlsx

I would like Brand to be a new column called “action field” and test initiative to be new column called “initiative”.

I have been able to successfully extract the initiative column however can’t seem to extract the action field in a logic driven automated way.

In past experience using other tools there was a way to "take everything to the right of the second " however I can’t seem to find a way to get the index of the nth character.
