The obj file extension is also related to Microsoft Visual Studio and used for one of its file types. This type of.obj files is used for object files, which are compiled but not linked.

LINK accepts .obj files that are either Common Object File Format (COFF) or 32-bit Object Module Format (OMF). Microsoft's Visual C++ compiler creates COFF ..obj files.

LINK automatically converts 32-bit OMF objects to COFF. However, there are limitations to OMF to COFF conversions. OMF can represent some things that cannot be represented in COFF. If there are errors when the linker converts from OMF to COFF, then you will need to use COFF .obj files instead of OMF .obj files as input to the linker.

Windows uses a special format for the executable (image) files and object files. The format used in these files are referred to as Portable Executable (PE) or Common Object File Format (COFF) files. The name Portable Executable refers to the fact that executable files can run on more than one platform. This article describes in detail the internal features of PE/COFF file formats and its parameters.
