Implement a -list (or similar) option without actual unpacking, displaying to the console the original file name, the original file size, and the original file's date and time
Wavpack isn't a file archiver. So (afaik) it just doesn't store original file name, size, date and time (although it is possible for wvunpack to deduce size of WAV file).Consider you compress BMP files to PNG. It is lossless, but PNG file doesn't contain neither original filename, nor original date/time. Nobody cares about it.
WinZip uses WV for comression of WAV's and ha a command line add-on, have you tried configuring that into TC?
-w “arc_filename=wavfile.wav” -w “arc_date=2008-11-27” ... etc.
