- Archives in CAB format: This function is not available.
- Archives in TAR or TGZ format (TAR.GZ): This function is not available.
- Archives in 7z format: The archive is fully compressed each time the function is called zipDeleteFile. This function is recommended when deleting a single file. If several files must be deleted from the archive, use zipDeleteFileList.
Reminder:    Only archives in ZIP, gzip, TAR and TGZ (TAR.GZ) formats are available.   Only ZIP archives are available.
Error codes The following error codes are returned: - 2: Access denied: user does not have sufficient rights.
- 3: The archive is corrupt.
- 4: The path does not exist in the archive.
- 5: Unable to write to archive.
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.
Important: After file deletion, files in an archive are re-indexed.. The indexes of the files 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 constant zipDisk is used, WDZ format memorizes the full path of the file (including drive letter), whereas ZIP format does not memorize the drive letter. Business / UI classification: Business Logic
