Hello,
MP3 file format uses
ID3 metadata[
^]. It allows information such as the title, artist, album, track number, and other information about the file to be stored in the file itself. The windows OS already has support for this file format and necessary code to retrieve the ID3 metadata. That's the reason you are able to see this information when you right click the file and select properties.
For windows to be able to retrieve such tags from your file you need to make windows aware of it and it's typically done via a shell extension. See following CP articles which will get you started
Once you have your shell extension ready, you will have to register it with the OS and against your file name extension.
Windows explorer will then use it to retrieve metadata from your file and display it. Please note that this is rather an over simplified explanation.
Regards,
