Have you encountered a problem with a ASM file? Don’t you know which program opens a file with this extension? You will find all the information you need about working with a ASM file here. In the further part of this page we have added a list of programs that should open your ASM file. It is enough you choose a proper application for your operating system, download and install it.


Files with the extension ASM are source code files in assembler programming language. An assembly language is a so-called low-level programming language that represents a human-readable form of machine language of a particular processor architecture (eg, x86, MIPS, PowerPC).

ASM files can contain the source code for entire programs or only parts, for example data segments or functions which are referenced in another ASM file, ie dH.

ASM files are merely text files that can be processed by a compiler called an assembler. They can be opened and edited in any text editor, however it is recommended to use editors with developer functions such as syntax highlighting for easier work.

Each processor architecture has its own machine language and thus also assembly language. In addition, the assembler compilers of a processor architecture sometimes have different syntax. Therefore, with an ASM file, you have to know the architecture and (depending on the architecture) the compiler, in order to be able to compile this file.

How to open a ASM file? Advice and guidance

Absolutely most often appearing reason that prevents you from opening the ASM file is the lack of a proper application to support it in your operating system. It is notably the first thing you need to address. When one of the programs to support a ASM file from the list is already installed, you can try to rerun the file. The system should display a message asking you to choose a primary application to support ASM files. At this point we are looking for disk space where the application was installed in and we can link it with a ASM file. Since then, our operating system will use the selected program to support all ASM files.

Other issues

Despite the described problem with ASM there may be many more problems. If the existing operations were not effective, get involved with the following matters:

- verify that the ASM file is not damaged and that it has been downloaded or copied in whole
- verify that the file has a file extension that has not been intentionally changed (for example, if it do not contain other information than its extension suggests)
- make sure again whether the ASM file type is linked in the operating system with a proper program
- make sure that the file is not infected with a virus and you have up to date software and drivers.
