Working with model settings files (IDL code)
The Reverser allows you to save the settings you have set in the Reverser to a model settings file. The model settings file records Reverser settings such as the root object, root directory, selected files for reverse engineering, search paths and directories to include.
On the Select Model page of the Reverser, you create or select a model settings file and specify whether you want to update that file on exiting the Reverser.
If you select a previously saved model settings file, the settings on each page of the Reverser default to the settings that were saved in the model settings file.
Note If you hover the mouse pointer over the Model Settings File box, a ToolTip provides the full path of the current model settings file.
