If you have a .zip file for Garry's Mod, follow these steps to install it safely:
"POBIERZ PLIK – GARRY'S MOD.ZIP" (which translates to "DOWNLOAD FILE – GARRY'S MOD.ZIP") is a typical name for third-party content packs or manual game installers. While many such ZIP files are legitimate community resources, you should only download them from reputable sites like GmodContent.com or the Steam Workshop to avoid potential security risks.
