Only start the extraction process from the first file ( .part01.rar ). Software like WinRAR, 7-Zip, or The Unarchiver will automatically detect the other parts and reconstruct the full file [1].
Do you have all the parts for this file (e.g., part01, part03)? If so, I can tell you exactly which tool to use based on your operating system (Windows, Mac, etc.) to get them extracted.
You must have all associated parts (e.g., 53381681.part01.rar , 53381681.part03.rar , etc.) in the same folder for the extraction to work [1].
For a solid archive (where the files are compressed together), you cannot extract or use the contents from part 2 alone.
Based on the file naming convention, "53381681.part02.rar" indicates this is [1].
