Standard game files contain video cutscenes, audio files (music, voice lines), and texture data. A version strips or re-encodes these assets using aggressive algorithms (like WinRAR or 7-Zip with ultra settings). The goal is to reduce the file size from, say, 1.1 GB down to 200 MB – 400 MB .
For absolute safety, follow this guide instead of searching for repacks.
