Properties Setting Label Colours


I am somehow stuck.

I would like to create a button which labels ALL SELECTED FOLDERS as well as ALL SUBFOLDERS and ALL FILES in ALL folders.
I have defined the colour and the name in the Properties (here e.g. set=green)

Properties SETLABEL=sets

works well for one selection: eather folder or files.

Can someone please give me a hint on how to do this!


It seems like there is no functionality to do that at the moment (?), so you have to process your folders one by one.
But you can use the flatview in each of those folders, which enables you to select all items and color them in one go.
