When converting music CDs or WMA files consistently, if you proceed consistently and, for example, create your own folder for each album or CD, you will find your music even with large amounts of data. Everyone usually has their own methodology for this. But if you create one folder per album, you can also save the cover of the CD as a *.jpg file here. The thumbnail of this image is then displayed in the folder overview. For this to work, you have to rename the image to folder.jpg.
