6_.rar

Alternatively, use unar which often handles multi-part files more reliably: unar filename.part1.rar . What is multipart archive - GitHub Gist

You do not need to extract each part individually. The extraction tool will automatically "stitch" them together:

The software will automatically read through all subsequent parts (2, 3, 4, 5, and 6) to produce the final, complete file. Navigate to the folder and run: unrar x filename.part1.rar .

You must have every part of the set (e.g., parts 1 through 6) in the same folder . If even one part is missing or corrupted, the extraction will usually fail.
