I want to thank all who have responded with help and advice. Here’s what I have learned and I hope you check me on this and let me know where I might be off base.
I see three tags involved with file names, Name, Filename, and Filename(name). Here is an example of each:
Filename: H:\iTunes\iTunes Music\Rubber Soul\Norwegian Wood.wav
Filename(name): Norwegian Wood
Name: Norwegian Wood
Filename tag is the entire path for the file that includes hard drive, folders, name, and file extension. It’s the roadmap to find the file. Filename(name) tag is the name subset of Filename tag. Name tag is independent of the other two tags and therefore changing it does not change the other two.
So, remembering I want to remove the first three characters in many names, I just want to change Name tags. As I understand it, I should not change Filename or Filename(name) tags because that would break the link between MC and the physical location of the file and MC would not be able to find and play the file.
Sound right to you?
