To open a file comparison window, choose Compare Files from the Search Menu to show a dialog box that prompts you for two files, source and destination files, to compare. To use a file dialog box to browse for the source and destination files, click their respective Choose buttons. You may also drag and drop text files into their respective boxes.

Make sure that the Compare Files radio button, shown in Figure 4.15, is enabled. This allows you to select files by using the Choose buttons.

Select the Case Sensitive checkbox to consider the case of letters as part of the comparison operation. To ignore the case of letter, deselect this checkbox.

To ignore extra space and tab characters while comparing text, enable the Ignore Extra Space checkbox. To take space and tab characters into account, disable the checkbox.

See "Folder Compare Options" for information on the folder comparison options.

To show the comparison window after choosing files and setting options, click the Compare button.
