Remarks

Use conditions

The files can be deleted from an archive if:

The archive exists (an archive is created by zipCreate).
The archive is accessible in read/write.
The archive is a single-part archive.

Caution:

Archives in RAR format: This function is not available.
Archives in CAB format: This function is not available.
Archives in TAR and TGZ (TAR.GZ) format: This function is not available.
Archives in 7z format: The archive is entirely compressed whenever zipDeleteFileList is called.

Only the archives in ZIP format are available.

Error codes

The following error codes are returned:

2: Access denied: the user has no sufficient rights.
3: The archive is corrupted.
4: The path does not exist in the archive.
5: Unable to write into the archive.

Subscript of files in the archive

Once the files have been deleted, the subscripts of the remaining files are modified. The subscripts of the files found after the deleted file are automatically decremented by 1.

Stored path

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

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

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 equivalent to the zipDirectory constant.

The directory and the disk are not stored in the archive path. Only the file name and extension are stored.

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

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


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