What is an INF file?

The INF file is a plain text file that contains all the information used by the device installation component to install the driver. This information includes the following:

  1. Driver name and location
  2. Driver version information
  3. Registry Information

The INF file format was developed as a plain text format by Microsoft. These .inf files are also known as setup information files and they are used for Windows applications, device drivers, and firmware components of Windows installations. When a user downloads a device driver installer or a Windows application installation package, the INF file is usually included.

 

These INF files are also included in the installation packages of most firmware updates and upgrades for Windows PCs. The data stored in these .inf files are typically details in plain text format, used by Windows application installers, hardware devices, and firmware components. These details are usually the directory location of the resources, the installation directory, and the requested file. When these .inf files are packaged with the device driver installer and firmware update or upgrade, these details may contain device configuration, default settings, and status logs.

These INF files may also contain information about software, device drivers, or firmware components. This is usually the installer creation and release date, version number and developer, and more. These .inf files can be opened with standard text editing applications such as Notepad.

Where are INF files stored on Windows 10? Every installed device must have an INF file. And these INF files are usually stored at C: WindowsINF.

Tip: Sometimes, the INF folder is hidden. In this case, you need to click on the View tab and tick the Hidden items option.

How to open and change the INF file?

Sometimes, you may need to change the INF files. For example, you received the error "The required line was not found in the INF" when you installed the driver. In this case, you can open the INF file to check what information is missing, find the relevant information from the manufacturer's website, and then modify the INF file. This way you can force install driver.

To open and modify the INF file, you can use tools like Microsoft Notepad. Alternatively, if you just want to open an INF file to view information, you can also drag and drop the INF file into your browser to open it.

Tip: INF files are susceptible to viruses, so you should scan your inf files carefully if someone sends them to you.
