: Right-click on only the first part (e.g., .part1.rar or the one with no number in the extension) and select "Extract Here" or "Extract to [Folder Name]" using a tool like WinRAR or 7-Zip .
: Often recommended for platforms like the Steam Deck.
: Ensure the naming sequence is intact (e.g., Archive.part1.rar , Archive.part2.rar ). If you renamed one part, you must rename the others to match for the software to recognize they belong together.
