This message is displayed when you are about to load a form design from an external file. You normally do this to import a script extension form file (.aqfrm) to your TestComplete project, as these files cannot be directly added to the project via the Add | Existing Item command.
To confirm the form import, click Yes and then browse for the .aqfrm file containing the form design you want to load. Your current form design will be replaced with the one you will select.
To cancel importing the form, click No.
