Do you have (part01, part03, etc.) in the same folder?

To successfully "prepare" or extract this file, you must follow these steps:

Ensure you have enough disk space (typically 60GB+) as the extracted folder will be significantly larger than the compressed RAR parts.

: If you get a "Checksum Error" during extraction, it usually means part02.rar or another segment is corrupted. You may need to re-download that specific part.

: Use a modern extraction utility like WinRAR or 7-Zip .

: You do not "prepare" part 02 separately. Instead, right-click on ELDEN.RING.Deluxe.Edition.part01.rar and select "Extract Here" or "Extract to..." . The software will automatically pull data from part 02 and all subsequent parts to recreate the full file.
