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 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	File location	zipNone	zipDirectory	zipDrive
zipAddFile("Archi", "File.txt")	C:\Temp\File.txt	File.txt	File.txt	File.txt
zipAddFile("Archi", "Data\File.txt")	C:\Temp\Data\File.txt	File.txt	Data\File.txt	Data\File.txt
zipAddFile("Archi", "D:\Data\File.txt")	D:\Data\File.txt	File.txt	Data\File.txt	D:\Data\File.txt

Remark: 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.

The zipDrive constant is ignored.

The table below presents the paths stored in the archive according to:

the access path to the file,
the stored path section.


zipAddFile	File location	zipNone	zipDirectory
zipAddFile("Archi", "\File.txt")	\File.txt	File.txt	File.txt
