About the FastSum user interface

The FastSum user interface is designed to provide an easy access to applications features. The major actions are embodied in two different ways allowing you to choose your own handiest one.

The following sections include a description of each user interface component, as well as links to more information about using each component.

Application Main Window

The main window contains four major areas:

Menu and toolbar

The toolbar is located at the top of the main window, under the menu bar, and contains shortcut buttons to commonly used tasks and features.


The Workspace is located below the toolbar and contains an Action panel, Information panel and Files list. You can easily create your first checksums by following the tips shown on the Action panel. Figure 1 shows workspace layout.

Please note that for a large amount of files you better use Calculation and Verification Wizards, they are specially optimized for it.
