These options control the status bar, which appears at the bottom of the Lister or file display.
If you turn this option on, the icon changes to a
icon. Clicking this icon lets you lock the folder format, to prevent it being changed automatically when you navigate to other folders. A brief animation is shown when the folder format is locked this way (just to let you know something has happened). In this mode, you need to right-click the icon to show the format menu.
You can tell Opus exactly what information to display on the status bar. By default a count of files, folders (and how many are selected) is shown, but you can configure the display to include much more information, including total playing time for music files and bar graphs to represent things like the proportion of space selected files would take up on a DVD. The text that tells Opus what to display on the status bar is known as its definition.
Four separate definitions can be configured. Which definitions are used depends on whether the Lister is in single or dual display mode, and in dual display mode whether you have selected to share a single status bar for both displays or for each display to have its own bar.
You can choose either:
The modes that govern which definitions are used are:
The definitions themselves are configured on the Definitions page.
