.O File Extension

A .O file is a Compiled C Object File, created by N/A.

Open with GNU Compiler Collection (GCC). Available for Linux, Windows, and Mac.

What is a .O file?

An .O file is a type of file that comes from compiling a C program. When you write a program in the C programming language, it's in a form that humans can understand, but not computers. To turn it into something a computer can run, it needs to be compiled. Compiling is like translating from human language to computer language. During this process, the compiler (which is a special program that does the translating) takes the human-readable C code and turns it into a compiled object file, which has the .O extension.

These .O files are like puzzle pieces of the overall program. They are not programs that you can run by themselves. Instead, they need to be put together, or "linked", to create an executable file, which is a file that a computer can run. This final file usually ends with .EXE.

To create and work with .O files, you need a compiler. Some popular compilers that can create these files include the GNU Compiler Collection (GCC) and the Tiny C Compiler. Both of these compilers can take your C code and compile it into .O files. Then, they can also link these .O files together to make an executable program that your computer can run.

In summary, .O files are important steps in the process of turning C code into a program that a computer can run. They are created by compilers like GCC and Tiny C Compiler during the process of compiling and before the final executable program is made.

Verification

Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
