GTA IV auto-saves after:
Do not rely solely on auto-save. It overwrites the same slot and may not trigger before a crash or mistake.
| Platform | Path |
|---|---|
| Windows (Steam/Epic) | %USERPROFILE%\Documents\Rockstar Games\GTA IV\savegames\ |
| Windows (Games for Windows Live) | %LOCALAPPDATA%\Microsoft\XLive\Content\ |
| macOS | ~/Library/Application Support/Rockstar Games/GTA IV/savegames/ |
| PS3/Xbox 360 | System storage → Saved Data Utility |
On PC, the F5 quick-save mod (via Script Hook) is popular but unofficial—use at your own risk.
