zipMerge (Function)

In french: zipRegroupe

Not available

Merges the different sub-archives found in a multi-part archive to create a single-part archive.

Example

See additional examples

MyArchive is zipArchive
// Open a multi-part archive
ResOpenArchive = zipOpen(MyArchive, "C:\MyArchives\Archive.zip")
IF ResOpenArchive = 0 THEN
...
// Merge the sub-archives found in a multi-part archive
ResMerge = zipMerge(MyArchive,...
"C:\MyArchives\SingleArchive.WDZ")
...
END

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. For more details on these error codes, see the Remarks.

<Archive>: Character string or zipArchive variable

Name of the archive to be used.
This name can correspond to:
the name of an archive, defined by zipOpen or zipCreate.
the name of a variable of type zipArchive.

<Archive destination>: Character string

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

Name of the Progress Bar control in a window. The progress bar will display the progress of the grouping.

Remarks

Use conditions

Remark: The merge operation can be performed if:

The archive exists (archives are created using 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 ZIP, TAR and TGZ (TAR.GZ) archives are available.

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.
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 is used to determine 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 merge the sub-archives (zipMerge) to get a single-part archive.

From a multi-part archive, you can only:

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).
