Running a File Comparison

To run a file comparison with DiffDog:

1.Open a new File Comparison window, if one is not already open. Note that, by default, DiffDog starts with an empty File Comparison window, in which case you can skip this step. To open a File Comparison window, select the menu option File | Compare Files or click the Compare files ic_compare-files button in the Standard toolbar.

2.Choose a comparison mode that is appropriate for the file types being compared (binary, text, XML, or extension-based). For more information, see Comparison Modes.
3.Select the files to be compared. There are various ways to do this, as follows:
In the left pane of an existing File Comparison window, click the Open ic_open button and select a file in the Windows Open dialog box.
Enter the full path to a file and click the Apply ic_apply button.

file_enter-path

Drag a file from the Windows Explorer into the pane.
Select a previously compared file from the drop-down list.

4.Repeat any of the steps described in step 3 for the right pane.

 

Alternatively, you can run a file comparison as follows:

 

1.On the File menu, click Open (alternatively, press Ctrl+O).

2.In the Open comparison dialog box, select Compare files .
3.Browse for the files to be compared and click OK.

 

Another way to run a file comparison is as follows:

 

1.In Windows Explorer, select the two files to be compared. (To select multiple files in Windows Explorer, hold the Ctrl key pressed while selecting a file.)
2.Right-click one of the files, and select Compare with Altova DiffDog command from the context menu.

 

By default, when the two documents to be compared are loaded into the comparison window, a comparison is automatically carried out. To enable or disable automatic comparison, do one of the following:

 

On the Diff and Merge menu, select the Autostart Comparison menu command.
Click the Autostart Comparison ( ic_autostart-comparison ) toolbar button.

 

In addition, comparisons can be explicitly started any number of times. To start a comparison explicitly, do one of the following:

 

On the Diff and Merge menu, select the Start Comparison command.
Click the Start Comparison ( ic_start-comparison ) toolbar button.

 

When editing documents, they are compared dynamically as you type if the Compare while Editing command is toggled on. To toggle this option on or off, do one of the following:

 

On the Diff and Merge menu, select the Compare while Editing command.
Click the Compare while Editing ( ic_compare-while-editing ) toolbar button.

 

If the Show Options Before Comparison command is toggled on, then the Comparison Options dialog box is displayed each time before the comparison is run (except when it is run dynamically by DiffDog while you edit). This is useful if you wish to run comparisons with different options. To toggle this option on or off, do the following:

 

On the Diff and Merge menu, select the Show Options Before Comparison command.
