Remarks

Splitting an archive

A multi-part archive is created by zipSplit. zipNbPartNeeded is used to find out the number of supports (diskettes for example) required to split the archive.

Multi-part archive

Using zipNbPartNeeded on a multi-part archive allows you to calculate the number of parts required for a new splitting.
