Thanks MTA. Quite new in posting forums like this.
I am using Windows 8. The Recuva that I was able to acquire's from the free download of the site. The file was deleted from a specific folder. Then after a couple of hours, I ran CCleaner.
After the deletion of the MP3, there were no major activities except for the running of the CCleaner. Yes, it's just 1 mp3 (unfortunately, I was not able to back it up...)
Thanks for taking time to answer my newbie questions and for being detailed about your advice.
