1. An electronic documentation file formatted according to the requirements of the destination operating system. Help files generally contain short instructions about how to perform certain features. They generally have fewer graphics than printed or electronic books of the same material. Help files reformat as needed to the screen window dimensions, and make heavy use of hypertext linking, pop-up boxes, and so forth. Help files are context-sensitive, which means that you can jump to a specific topic within the help file directly from the applications dialog and menu interface, etc.
