In Vista, when you open a folder in Detail View it shows some default columns like "Name", "Date modified", "Type" and "Size". It is also possible to add other columns like "Categories". But this column gets added to the folder view only in the current folder. Is it possible to set it to be displayed for subfolders as well?
Have you tried this?
In Windows Explorer, click the Organize button and on the menu, click the Folder and Search Options item.
Which brings up the Folder Options dialog:
On the View tab, in the Folder Views section, click the Apply to Folders button.
