"Computer Homer" here...hope you will bear with me. Had to install new HD. So I consolidated music files (different formats) from different HD onto the new drive. Then created new master music file with dedicated sub-folders for each artist. Music library has 800 plus files; some are shown in BOLD black and some are in gray. When you try to open a "gray" file it messages the source file cannot be found and would I like to try to locate it and then it gives the previous file location on an old HD which is no longer connected to my computer. I used MB's FILE>Scan folders for New File>C\>add to library. However, this does not get the file back into the master library. Well the file does exists and can be accessed and played out of the master music file>specific artist>song title.
What MB operation do I need to perform to get all relocated files recognized in library?
