How should Downloadable Content files be named?

Downloadable Content uses a similar naming structure: 

1. Your product number (do not use ISBNs)
2. An underscore (_)
3. The full title of the piece

Examples:

• JWP123_The Title of the Piece.pdf
• JWP123_The Title of the Piece.mp3
• JWP123_The Title of the Piece.zip

If a ZIP folder contains multiple files, name the ZIP file using the same convention.
