If the file is safe, you can use specialized tools to see what is inside without fully extracting it:
: Upload the file to VirusTotal to check it against dozens of different antivirus engines simultaneously.
: Right-click the file and scan it with a tool like Microsoft Defender or Malwarebytes .
: "CWS" often stands for "Continuous Wave System" in engineering or "Chrome Web Store" in tech, but without context, these are just guesses.
