Code Compare allows using folder hierarchy comparison and synchronization, which enables you to compare and merge entire directory trees. It can be useful for detecting changes in different versions of source code or web pages. Besides, this functionality can help you to compare and merge branches taken from your version control system.
To start folder comparison do the following:
In Windows Explorer, locate the other folder you want to compare, right-click it and in the context menu choose Compare with “<folder name>“ (i.e. folder you selected in the previous step).
Start Code Compare, specify the required folder paths in the Folder Location combo boxes and press ENTER.
Navigation between differences can be performed by means of the Previous/Next Change buttons either in the Code Comparison toolbar, or in the bottom outer corners of the documents. For more information about navigation between differences, see the Keyboard Shortcuts article.
Folders are compared in compliance with Code Compare options.
Code Compare allows you to set folder filters in order to omit certain files or folders from comparison. The following filtering criteria can be used: you can leave out system/hidden files, or files exceeding certain size, or files having certain extension, etc.
To access these settings, open the Tools menu, select Options, in the displayed Options dialog box expand the Code Compare node, then expand the Folder node and, finally, navigate to the Filters page.
These settings influence comparison performance and precision. You can select rules-based comparison and choose to ignore case, whitespaces or line breaks, or you can select binary comparison to open and compare files at the byte level. Besides, you can choose not to compare files with equal size and timestamp.
To access these settings, open the Tools menu, select Options, in the displayed Options dialog box expand the Code Compare node, then expand the Folder node and, finally, navigate to the Comparison page.
You can customize the display options in order to highlight modified folders only when collapsed, expand changes to a certain level automatically, or show details on files and folders like size or modification date.
To access these settings, open the Tools menu, select Options, in the displayed Options dialog box expand the Code Compare node, then expand the Folder node and, finally, navigate to the Miscellaneous page.
Folder comparison uses standard colors for difference highlighting.
You can merge folders with the help of Copy to Left and Copy to Right items of the popup menu.
If you want to compare different file revisions just double-click on the file or select it and press ENTER.
