Syntax

<Result> = zipMerge(<Archive> , <Archive destination> [, <Progress bar management>])

<Result>: Integer

0 if the sub-archives have been merged,
an error code (value greater than 0) otherwise. See the Notes for more details.

<Archive>: Character string (with quotes) or zipArchive variable

Name of archive to use.
This name can correspond to:
an archive name, defined by zipOpen or by zipCreate.
Versions 15 and later
the name of a zipArchive variable.
New in version 15
the name of a zipArchive variable.
the name of a zipArchive variable.

<Archive destination>: Character string (with quotes)

Physical path of new single-part archive (up to 260 characters). This path must contain the name of single-part archive to create. If the extension (.WDZ or .ZIP) is not specified, the extension corresponds to the initial extension. You have the ability to specify the same path and name as the split archive: the split archive will be overwritten by the merged archive.

<Progress bar management>: Optional character string (with or without quotes)

Versions 21 and later
Name of Progress Bar control found in a window. The progress bar will display the progress of grouping.
New in version 21
Name of Progress Bar control found in a window. The progress bar will display the progress of grouping.

Remarks

Use conditions

Note: The merge operation can be performed if:

The archive exists (an archive is created by zipCreate).
The archive is a multi-part archive.
The archive is not in "CAB" format, in "RAR" format or in "TAR" or TARGZ" format.

Reminder:

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

Error codes

The following error codes are returned:

1: The path passed in parameter does not exist.
2: Access denied: the user has no sufficient rights.
3: The archive is corrupted.
6: The sub-archives are not arranged in order.

The message corresponding to the error code is returned by zipMsgError.

Closing the archive

Once zipMerge has been used on an archive, this archive is not closed. You must use:

zipClose to close the multi-part archive.
zipOpen to open the new single-part archive.

Number of parts

zipNbPart enables you to find out the number of sub-archives in a multi-part archive.

Actions that can be performed on a multi-part archive

Some archiving functions can only be used with single-part archives (add and delete files, create a self-extracting executable, etc.). To perform these operations, simply group the sub-archives (zipMerge) to obtain a single-part archive.

From a multi-part archive, you only have the ability to:

Merge the different parts (zipMerge).
Get information about the archive and the files in the archive (zipExtractPath, zipInfoFile, zipListFile, etc.).
Extract the files (zipExtractFile, zipExtractAll).

The multi-part archive is found on diskettes

If the different sub-archives are found on diskettes, the next diskette will be automatically requested via a dialog box when the sub-archives are merged. An error will occur if the merge operation is canceled by the user (the multi-part archive is not found).
