Remarks

Reminder

    Subscript of files in the archive

    When a file is added into an archive, a subscript is automatically assigned to the file. This subscript corresponds to the order in which the files are included in the archive. To select a file found in the archive, you can use:
    • the subscript of the element (the subscript of an element is returned by zipFindFile).
    • the stored path of element.

    Stored path

    The table below presents the paths stored in the archive according to:
    • the access path to the file,
    • the stored path section.
    The current directory is: "C:\Temp".

    zipAddFile("Archi",
    "File.txt")

    zipAddFile("Archi",
    "Data\File.txt")
    C:\Temp\Data\File.txtFile.txtData\File.txtData\File.txt
    zipAddFile("Archi",
    "D:\Data\File.txt")
    D:\Data\File.txtFile.txtData\File.txtD:\Data\File.txt
    Note: If the zipDrive constant is used, the WDZ format stores the full path of the file (including the drive letter) while the ZIP format does not store the drive letter.
