Remarks

Reminder

Only archives in ZIP, gzip, TAR and TGZ (TAR.GZ) formats are available.

Index of files in the archive

When a file is added into an archive, an index is automatically assigned to the file. This index corresponds to the order in which the files are included in the archive. To select a file in the archive, you can use:

the index of the element (the index of an element is returned by zipFindFile).
the stored path of the 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 constant zipDisk is used, the WDZ format memorizes the complete path of the file (including the drive letter), whereas the ZIP format does not memorize the drive letter..

The zipDrive constant is ignored.
