It's still a bit difficult to answer since you didn't give exact information (exact filename paths, drive letters, cover art location in MC options, etc).
So I must guess:
- Your cover art files are in the default MC cover art folder on your C: drive (= your old drive). They are all named in "Artist - Album.jpg" style (MC uses that when it downloads images).
- Your new drive is E: (D: is the CD/DVD drive)
- You are not going to remove the old drive (C:) from your system
- You are not going to change your MC installation on your old (C:) drive
- The images in the old location are still working (even the music files are already moved).
- You would like to move your cover art files to some folder on your new drive (E:), for example to "E:\Cover Art".
A:
Copy the current cover art folder to your new drive with Windows Explorer or by dragging it in MC tree > Drives and Devices. Change the cover art folder in MC options to be correct.
Select all files in your MC library > right-click > select: Image > Remove Cover Art (MC asks if you like to delete the files. Answer no. You can delete the old folder later.)
Select the same files again and right-click > Image > Quick Find in File / Cover Art directory.
Remember to make a library backup first.
This is a way to do it internally with MC. Some other options:
- KingSparta's plug-in for moving the covert art files to the music file folders. (Though, I think it works only with MC11)
- It is also possible to export your library data and edit the information with a word processor and import the data to a new library, but it is a bit more complicated.
