Press the [cmd+i] on [yoursound.wav] to open up the [Get Info Window]...
contains the line [Where:] you will copy the text folder path.
[copy] the [/Users/[Account name]/Documents] then typing [/yoursound.wav] on your WAV sound path together.
Sometime you will see path [/Volumes/yoursound.wav]
that is your other hard drive beside the main hard disk.
I recommend that you move yoursound.wav into your Users/[Account name]/Documents.
What if your second hard disk disconnect, it will not play the WAV sound properly.
