Clicking this menu item will open a file dialog box, where you can select the file for which the MD5 checksum should be calculated. Depending on the size of the file (and the speed of your computer) it may take a couple of seconds until its whole content had been read, and all the calculations are done. In the meanwhile you will see a message in the main window. The result will then be displayed. During the processing the application is not be available for any user input.
This menu item just closes the application. Please note that you can run multiple instances of this software without any problems.
As soon as a calculation result is available and shown in the window the complete content can be copied to the Windows clipboard. Any previous content will be overwritten. This menu item is initially disabled, before any file was processed.
This will activate the HTML help system, which closes automatically when the application ends.
Shows information about this software, including the version information.
After an MD5 checksum of a file was calculated you will see its textual presentation in the window. The format is the hexadecimal encoding of each of the 16 bytes of an MD5 hash, separated by spaces. This makes it easier to read and compare.
The application is drag and drop enabled, which means that in the Window environment you can drop a file into the main window. This has the same effect like opening it manually. The same functionality is supported for the command line, so if you e.g. have a shortcut to the executable you can drop a file on it, MD5 Checksum will then start automatically and start processing immediately.
