Based on the file extension and your phrasing "put together piece," here is how you can proceed:

: If you received this file unexpectedly or from an untrusted source, do not open it . Compressed files like .rar are frequently used to mask malware or "zip bombs" designed to crash your system.

Could you share or any other clues (like a password hint or a website URL)? That would help me give you a more specific answer.

: The name suggests it might be a split RAR volume . Check if you have other files named like BWW.part1.rar , BWW.part2.rar , etc. You need all parts in the same folder to "put together" the final piece using a tool like WinRAR or 7-Zip .
