Archive files ( .rar , .zip ) are common vectors for malware.
Only open suspicious legacy files in a virtual machine (VM).
Run the file through VirusTotal before opening.
If you found this file on a forum or as an email attachment, exercise caution:
Files with .rar extensions in this niche often contain C++ or Pascal source code for retro-computing projects found on sites like Archive.org . ⚠️ Safety Warning
