Syntax

Adding a file while specifying the path section to keep Hide the details

<Result> = zipAddFile(<Archive> , <File path> [, <Path section to keep> [, <Progress bar management>]])
<Result>: Integer
  • 0 if the addition was performed,
  • an error code (value greater than 0) otherwise. For more details on these error codes, see the remarks.
<Archive>: Character string (with quotes) or zipArchive variable
Name of archive into which the file will be added.
This name can correspond to:
<File path>: Character string (with quotes)
Path of the file to be added to the archive (260 characters maximum, 90 maximum in the case of an archive in TAR or TGZ format (TAR.GZ)). This path can be a full path or a path relative to the current directory. The wildcard characters (*,?) are not allowed in the file name.
The size of this file must not exceed 4 GB. Otherwise, an error occurs.
<Path section to keep>: Optional constant
Indicates the section of the file path that will be kept in the archive:
zipNoneKeeps the file name and extension. For example: FileName.pdf
zipDirectory
(Default value)
Keeps the different directories of the file path as well as the file name and extension. For example: \Directory\Files\FileName.pdf
zipDriveKeeps the full and absolute file path (name of disk, name of directories, file name and file extension). For example: C:\Directory\Files\FileName.pdf
For the ZIP format: This constant has no effect.
For the 7z format: This constant and zipDirectory will have the same effect.
If you are using an archive in .CAB format, only the zipNone constant is taken into account. Indeed, the .CAB format cannot be used to save the paths inside the archive.
<Progress bar management>: Character string (with or without quotes)

Remarks

Use condition

Adding files into an archive can be performed if:
  • The archive exists (an archive is created by zipCreate).
  • The archive is accessible in read/write.
  • The archive is a single-part archive.
  • The size of the file is less than 4 GB.
Caution:
  • Archives in CAB format: The files must be added immediately after the archive creation. This format cannot be used to add files into an existing archive.
  • Archives in 7z format: The archive is entirely compressed whenever zipAddFile is called. This function is recommended when adding a single file. If several files must be added into the archive, use zipAddFileList or zipAddDirectory.
The maximum number of files that can be included:
  • in a WDZ file: 232-1.
  • in a ZIP file: 65535.
  • in a CAB file: 65535.
Reminder:

    Compression level of ZIP or 7z archives

    The files added into an archive in ZIP or 7z format are compressed by default. The compression level of files added into an archive can be modified by zipCompressionLevel.

    Error codes

    The following error codes are returned:
    • 1: The path passed as parameter does not exist.
    • 2: Access denied: the user has no sufficient rights or the file is currently used. If the file to insert is a HFSQL data file, it must be closed by the following code:
      HClose(FileName)
      Multitask() // Waits for the effective file closing
    • 3: The archive is corrupted.
    • 4: The path does not exist in the archive.
    • 5: Unable to write into the archive.
    • 7: The file is already found in the archive.
    • 8: An archive cannot be added to itself. For example, "MyArchive" cannot be added to "MyArchive".
    The message corresponding to the error code is returned by zipMsgError.

    Adding a file that is already found in the archive

    An error occurs when adding a file that is already found in the archive. A file is identified according to the path saved in the archive. Therefore, two files with the same name and with the same relative path cannot be added into an archive.
    For example, the zipNone constant cannot be used to add two files with the same name found in different directories.

    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 element subscript (remark: the subscript of an element is returned by zipFindFile).
    • or the path of the element saved in the archive.

    Path kept (archives in WDZ or ZIP format)

    The array below shows the paths kept in the archive according to:
    • the access path to the file,
    • the path section to keep.

    Reports and Queries

    Progress Bar

    In Windows, to view the progress of file addition and compression, an event must be branched on CompressProgressBar (1174). When this message is received, the _EVE.wParam variable contains the percentage of file already compressed.
    Caution: This event is not supported if the call to zipAddFile is performed in a secondary thread.
    Versions 21 and later
    From version 21, <Progress bar management> can also be used to manage the progress of file addition.
    New in version 21
    From version 21, <Progress bar management> can also be used to manage the progress of file addition.
    From version 21, <Progress bar management> can also be used to manage the progress of file addition.
    Special case: Archives in 7z format: The compression being global, the percentage of compression for a single file is not known (_EVE.wParam variable). Only the _EVE.lParam variable that contains the global progress is refreshed.
