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

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

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).
