# External Format General Settings

To compare files using another application, define an external format. The Mask should be the set of file types it handles. The Quick compare command line will be used whenever rules-based comparison results are needed. The return code should be 0 for a match and 1 for a mismatch. The Compare view command line will be used whenever a comparison view is needed. The Quick merge command line will be used whenever rules-based merge results are needed. The return code should be 0 for a match and 1 for a mismatch. The Merge view command line will be used whenever a merge view is needed. The Description can include any text you want.
