: Indicates that the archive is a "split" volume. Because modern games often exceed several gigabytes, they are divided into smaller pieces (parts) to facilitate easier uploading and downloading.
The filename follows strict conventions used within the digital distribution scene to ensure data integrity and ease of use:
