This naming convention indicates that a large original file or collection of data has been "split" into smaller, manageable chunks.
A primary feature of a file named is that it is a multi-volume archive (also known as a split archive). Key Feature: File Spanning (Split Archives)
Splitting files into parts like this is often done to bypass file size limits on email attachments, cloud storage, or older file systems, and to make it easier to resume interrupted downloads.
