I just experienced some odd behaviour. Here's the sequence of events:
1. From the My Computer branch in the MC9 root, I edited the properties of a series of files int the I:\Unchecked\Kinks, The\Lola Meets Powerman folder.
2. After editing I imported them into the library using the right click import feature.
3. Still in the My Computer branch, I dragged and dropped the "Kinks, The" folder from 1 to the "H:\MusicBack\Other 1" folder. Before the move, a "Kinks, The" folder existed under the destination path, but there was no "Lola..." folder underneath it.
3. Go to the Artist/Album view in the database. Album existed, and the files each appeared to show the correct location (H:\Musicback 1\Other1\Kinks, The\Lola Meets Powerman\01 - .....). However they wouldn't play and couldn't be edited.
4. After going into Windows Explorere, the files were actually copied to " H:\Musicback 1\Other1\Kinks, The\Kinks, The\Lola Meets Powerman\01 - ....."
5. Moved the files back to where they should have been, and everything works.
I think there's a bug somewhere in the Move feature....
