A multi-part zip file is a zip file that is split into multiple files, all in the same folder. All the parts of a multi-part zip file usually have the same filename but with a different (numbered) filename extension. A multi-part zip file can be manually "converted" to a spanned zip file by placing each part on a separate floppy disk or other removable media and renamed to the same filename and filename extension. A conversion such as this, though, works only if each part of a multi-part zip file is small enough to fit on one disk, and is not guaranteed to take up all available space on a disk as when a spanned zip file is created by Xceed Zip Compression Library.
