Thanks, Monica. Wonder how you were able to edit the ID tag info? It just gave me option to "remove properties and personal information" but didn't allow me to edit it.
I am running Windows 7 on my home computer. In order to display my suffix's (which I could then edit), I did the following:
1. Open Folder Options by clicking the Start button, click Control Panel, click Appearance and Personalization, and then click Folder Options.
2. Click the View tab, and then, under Advanced settings, do one of the following:
To hide file extensions, select the Hide extensions for known file types check box, and then click OK.
To display file extensions, clear the Hide extensions for known file types check box, and then click OK.
After I clicked the OK tab, the upper-case .MP3 that was showing in your file, automatically turned into a .mp3 (lower-case).
