Some RAR files can be parts of multi-volume sequences. In WinRAR you can split a huge archive to a few smaller files, which are called volumes. They may have extensions .rar (the first volume), .r00, .r01, ..., or .part1.rar (the first volume), .part2.rar, ..., etc. If you need to unpack volumes, place all them to the same folder and start extraction from the first volume.

So, open only Part1.rar and hit Extract. It will automatically extract all files and folders that are spanned across all parts of the .RAR archive.

Got it, thanks
