GTA4和DLC同时玩的方法！
原理不说了，gta4我一直玩，刚打了4G高材质和汉化补丁，不想升到了1.0.6了，有想玩dlc，建立了两个批命令脚本方便启动.
侠盗飞车4.bat
cd C:\Users\admin\AppData\Local\Rockstar Games\GTA IV\Settings
copy SETTINGS_y.CFG SETTINGS.CFG
d:
cd "D:\Program Files\Rockstar Games\Grand Theft Auto IV\"
start NoRGSC.exe
exit
侠盗飞车4资料片.bat
cd C:\Users\admin\AppData\Local\Rockstar Games\GTA IV\Settings
copy SETTINGS_d.CFG SETTINGS.CFG
d:
cd "D:\Program Files\Rockstar Games\Grand Theft Auto IV\EFLC"
start LaunchEFLC.exe
exit
SETTINGS_y.CFG是原版配置文件拷贝
SETTINGS_d.CFG是资料片配置文件拷贝
在win7测试成功，切换很方便。
