You can use the File Compare/Merge options to configure its behavior and screen display. You can only set options in the main and standalone File Compare/Merge windows. The options available depend on which version of File Compare/Merge you are using. For example, if you are using the main File Compare/Merge in the client, folder options are not available since you can not compare folders in this version. All options are available in the standalone File Compare/Merge.
To set File Compare/Merge options
