What is an I file?

File generated by the Microsoft Visual Studio compiler when compiling a Visual C++ project; contains the output from the preprocessor operation; may be used to diagnose and fix compilation errors.

More Information

If you want to generate an ".i file" from a source file, you can right-click on the file and select "Properties." Then select C/C++ → Preprocessor in the Properties tree. Finally, deselect "No" for the "Generate Preprocessed File" option.

When you compile the file, an ".i file" will be created. However, this setting may also prevent the compilation process from completing. Therefore, "Generate Preprocessed File" should be reset to "No" when you want to compile your project.
