This information shows when FRD starts saving a file (after all wait times). Could you make it shows earlier? Maybe even when checking file on server to not require user action later. But in this case "apply for all" option may be useful. ;)

The final file name is determined only right before the download starts (some services don't provide the correct file name until that).

You can change the default action for this situation
"Options > Preferences - General"
at the bottom "If a filename already exists" has options = Rename, Overwrite, Skip/Cancel, Ask
