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 or TGZ (TAR.GZ) format: This function is not available.
Archives in 7z format: The archive is entirely compressed whenever zipDeleteFile is called. This function is recommended when deleting a single file. If several files must be deleted from the archive, use zipDeleteFileList.

Reminder:

Only the archives in ZIP, TAR and TGZ (TAR.GZ) format are available.
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

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.

Important: 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

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.

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.
