There's a rather good chance that the info on artist and title is stored in the file itself. Then your mp3-player might be able to show them. Album is more difficult, because it's not a property of the mp3-file: a certain track can be sold in different albums.
So just try what works and what doesn't work when you copy from the directory.
The structure of a library, alas, isn't standard. So probably you would need to install a copy of QMP in your car audio installation to be able to read it. That doesn't seem very practical. What does the manual of that installation say about the possibilities of organizing your music on a stick?
A better way might be to switch to iTunes and iPods. Those are synchronized. Then you need a car audio you can plug your iPod in to have that information shown.
Really a novice here when it comes to this, so I need some help. I am using Quintessential Music Player to organize & play my MP3's. What I am trying to do is to simply copy my music (MP3's) over to a flash drive. I want to be able to do this directly from the QMP's song list instead of from the directory where they are stored on my computer. The reason for that is that when I look at these music files which are stored under My Documents > My Music, half of my songs only show the song title, not the artist or the album title. I want all of that to show in my car when I'm playing them. IN QMP, when I look at it's songs list, everything about that song shows & I want the same thing on my flash drive. Can someone help me here?
