Microsoft Linker ordering instructions

File type category:
Miscellaneous file

Date updated: November 4, 2026

The seg file extension is associated with Microsoft LINK, the linker that combines Common Object File Format (COFF) object files and libraries into an executable (.exe) file or a dynamic-link library (DLL).

This file is an input instructions file rather than a compiled program. The linker reads its contents to apply ordering instructions while creating the executable or library.

How to open seg file?

A seg file is a text-based linker input file and can usually be inspected with a plain-text editor. Opening it for normal use is not necessary; it is intended to be supplied to Microsoft LINK during a build.

How to convert seg file?

A seg file is not normally converted. It contains linker instructions, so its contents should be edited as text or replaced with equivalent linker input rather than converted to another file format.
