More information in List views
QIn the Finder’s List View, I can choose to display additional information such as duration for some folders but not others. How can I extend that to any folder?
AThe Finder’s list views can be customised to show information about files in certain folders. To try this, open one of the specially designated folders in your Home folder, such as Movies, Music or Pictures, and show it as a list. ≈-click in the header bar of the window to see the column menu, and there are special properties shown below the divider, such as Dimensions and Duration. These are controlled in the Finder preferences file, and not something you can readily customise. The Finder uses the folder name to determine which of several suites of properties to offer in that menu. For example, name a folder in Documents as Movies, and its list view properties will resemble those in your standard Movies folder. You can get this to stick even when that folder’s name changes again, and that’s one way of effectively adding properties to the lists elsewhere.
This is different from the categories listed as Information below the thumbnail shown when a file is selected in column view, which is determined according to the file’s type, and set in the same Finder preferences file.
