I suggest you create a new folder in your hard drive. When the .wav file comes in, save it in the new folder which you might simply label as WAV . To save on hard disk space, I usually convert .wav files to .mp3 using Audacity, then convert the .mp3 files using RealProducer10. Both are freeware . Instead of using RealPlayer Gold 10, I use Real Alternative which is also a freeware. Now, if you get to a really difficult ESL dictator, try running .mp3 using Audacity in transcribing the audio file then proofread using Express Scribe. Worked for me
