      Extra field length (m)

    • fileComment: string

      File comment

    • fileCommentLength: number

      File comment length (k)

    • localFileHeaderRelativeOffset: number

      Relative offset of local file header. This is the number of bytes between the start of the first disk on which the file occurs, and the start of the local file header. This allows software reading the central directory to locate the position of the file inside the ZIP file.

    • signature: ArrayBuffer

      Central directory file header signature = 0x02014b50

    • startingDiskNumber: number

      Disk number where file starts
