Notes about the 4MI file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The 4MI file type is primarily associated with '4MI' by GTA4MODS.COM.
GTA 4 Mod Installer was the first mod installer for GTA IV.
4MI automatically scans the mods folder and populates your mod list. All there is left to do is select which mod you want to install and click install. In this tab you can also uninstall and remove mods.
If at any time you download a 4MI package via another site, that you have placed in the mods folder, you can use the refresh button to refresh your mod list.
