Hi,
No, files are not duplicated, they have different content. In that sample project, for example when the input is invalid files are executed in the following order:
...
Callflows_Dialer_MF_EnterDestination.vxml
Callflows_Dialer_MF_EnterDestination_InvalidInput_DebugInfo.aspx
Callflows_Dialer_MF_EnterDestination_Invalid_Input.vxml
Callflows_Dialer_MF_EnterDestination_Invalid_Input_DebugInfo.aspx
Callflows_Dialer_MF_Operator.vxml
Callflows_Dialer_MF_Operator_DebugInfo.aspx
...
The file Callflows_Dialer_MF_EnterDestination_InvalidInput_DebugInfo.aspx generates debug information about executing the branch "Invalid Input", and the following file executed is Callflows_Dialer_MF_EnterDestination_Invalid_Input.vxml, which is the first file in the invalid input branch.
File names are very similar, but they are different files with different purposes....
Thanks for noticing this, in this case this is not a bug, but your are helping us to improve the VAD, and we appreciate it very much!
Regards.
