Can the fonts in the Folder Tree be made Large?

Does anyone know how to make the fonts in the Folder Tree Large ... Like on the right size of the screen you hold down Control button and move the middle wheel on the mouse up or down.

Any HELP you can offer will be much appreciated .... CHEERS !!!

I don't think you can zoom the folder tree, but you can change the font size in the preferences:

I will give the a try ....... Thanks
