Once <zipArchive variable>.Merge has been used on an archive, this archive is not closed. You must use:

Number of parts

The zipNbPart function allows 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 subarchives (<zipArchive variable>.Merge) to obtain a single-part archive.
From a multi-part archive, you only have the ability to:

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).
