I also need to be able to count how many minute's worth of recordings
do these files  hold. For this, manually, I do a search for *.wav files
in a particular folder, and then play them in winamp, to see total
minutes.

Can a search and play be a part of the macro/vba code?

These are actually dictations from doctors, to be distributed to
Medical Transcriptionists. I just need to be able to keep track of the
minutes worth of recordings per doctor, and how many minutes have I
distributed to which person.
