    1. Does scan clear the entire user “disk-related” Library software data & then recreate all media software structures from scratch, in accordance to the current disk folders/files’ definitions
    2. Is “Initialization” needed before/after a scan?

  • What does rescan actually do
    3) Does a rescan notice changed file tags?
    4) Does a rescan notice a deleted album, song,…?
    5) Does a rescan notice an added album, song,…?
    6) Does a rescan notice an added file tag?
    7) Is “Initialization” needed before/after a rescan?
