If this option is enabled, a search for subject EAs is performed during directory scans. This option may also be toggled from the Directories menu as a cascaded option of Refresh. When this option is toggled on, a refresh of the Files window occurs and the Show Subjects option in the Window Options menu is enabled. The Show Subjects option may then be set on or off without affecting the Load Subjects option setting.
The effect of searching for the subject EA is an increase in scan search time. The measurable effect will vary with hardware performance and may or may not be noticeable. It has therefore been made an option. The use of this option will be dependent of your use of this feature.
