i have a suggestion for a change to your program that would make it more useful in some circumstances. Your Audio Converter Pro program stops when it discovers an imcomplete file and asks for instructions. The user must select to skip the file, convert it, or "convert all incomplete files". I suggest it would be a help to have an option to "skip all incomplete files". That way, I could set the program to convert a batch of files, and know that when I return, I will not discover the program has stopped early in the process, and further, I would have a set of converted files that I knew were all complete.
It would avoid the irritant of listening through half of a song only to learn that the rest of it is not there (because the MP3 file was incomplete - not a failure of your program, obviously).
Best of all, give the user the option to set the "do not convert imcomplete files" at initial setup, rather than after the first problem during an individual episode of converting files. That way, the user would not return to discover the program had stopped awaiting further instructions.
