Modify the Directory Comparison Options
When comparing directories, the comparison mode you choose determines how the content of the directories in the left and right pane of the Directory Comparison window are compared. The basic comparison mode switch is the Quick Comparison toggle. In order to access Text Comparison Mode, or XML Comparison Mode, or Binary Comparison Mode, or Extensions Comparison Mode, Quick Comparison must first be toggled off.
You can also define which types of files will be displayed in the Directory Comparison window by applying a filter. In addition, the Diff and Merge menu offers several toggle commands which can be switched on or off via the menu:
•Show Options Before Comparison
•Support Recently Compared Pairs
General options for the comparison of directories are furthermore available in the Directory comparison tab of the DiffDog Options dialog box.
| Note: | If a new Directory Comparison window is opened, it assumes the comparison options of the last comparison window (file or directory) to have had any of its comparison options modified. |
