In the world of visual novels (VNs), a "rip" usually involves:

: While the 7-Zip software itself is widely regarded as safe, the contents of a third-party .7z file can contain malicious executables. Always scan such files with VirusTotal before opening.

: Files found on unofficial "rip" sites are often hosted on expiring or hijacked domains, which can lead to malware infections.

: Deleting "bloat" such as multiple language packs, unused assets, or lowering the quality of video/audio files to save space.
