: If any single part is corrupted, the entire extraction will usually fail.

: It is the mandatory starting point for extracting the contents. The extraction software uses the information in "part1" to automatically locate and join the subsequent parts (e.g., na18.part2.rar ).

: If a part is missing, the extraction will fail with an error like "Next volume is required".

: Use software such as WinRAR, 7-Zip , or Unzip One .
