AlbumWrap (ALBW)

File Format
Name	AlbumWrap (ALBW)
Ontology	Electronic File Formats Audio and Music AlbumWrap (ALBW) ; ; ;

AlbumWrap lets you combine multiple MP3s into a single MP3.

The resulting file can be played in most mp3 players and still extracted back to the original files.

The extract functionality is often problematic and it is recommended to use other tools like Alba Extractor to work with ALBW files.

The format is also very fragile, do not rename files after creation and don't edit the ID3 tag
