In the Application tab of the DiffDog Options dialog box, you define the startup options of the application.
Three radio buttons are available to define whether DiffDog starts up with an empty File Comparison window, an empty Directory Comparison window, or no comparison window.
If the Allow multiple instances check box is deactivated, starting DiffDog when an instance of DiffDog is already running causes a new comparison window (file, directory, or empty) to open in the already running instance of DiffDog.
The Show Program Logo option—if checked—displays the splash screen (logo) when DiffDog starts.
Windows Explorer Integration
If the Add "Compare with Altova DiffDog" entry to the Windows Explorer context menu check box is activated, you can start a file or directory comparison directly from Windows Explorer by selecting the respective files or directories and choosing Compare with Altova DiffDog from the context menu.
You can select the encoding with which to open an XML file or non-XML files, respectively, where the encoding cannot be detected.
The Show Program Logo option—if checked—displays the splash screen (logo) when DiffDog starts. The Show on print becomes enabled and can be switched off after you have registered your application. If this option is checked, the program logo is printed with the active document or directory-comparison result, when this is printed.
