1. Borland C++ Pre-processor intermediary file.
2. GCC pre-processed C file.

A .i file is a temporary file generated using the GCC compiler (which is used to compile C and C++). The GCC compiler does not normally generate a .i file but will do if directed to do so (via the -save-temps switch).

The .i file contains the output of a C source file after pre-processing has been performed. A .i file can in turn subsequently be used by the GCC compiler to save on compilation time (as pre-processing is not required).
