Since I've had my Intel Mac, the icons for the sound files have "gone vanilla", probably as a result of them never having had a file extension on their name. If I drag them onto the Quicktime player icon they decline to open. However, dragging them onto Sound Studio works perfectly every time and shows that the data inside the files is still good and playable.
My two questions are:
1. Is there any historical information that reveals what the system 7 sound file format *is*? If you recall systems 9 and earlier, you double clicked them in the Finder and they just played, not even requiring an application.
2. Although it's a relief to know that the data inside these old, but valuable files is still readable and playable one by one in programs like Sound Studio, my interest in Switch is its ability to do batch conversion. I would love to be able to drag a folder containing a complex nesting of further folders and these sound files onto Switch and have it convert all the files "in place" (ie preserving the folder structure), and for each sound file "blah" (no extension), putting a new one beside it "blah.mp3" (for example).
