ASM file extension - Assembler source code

What is asm file? How to open asm files?

File type specification:

Source code and script file type icon Source code and script file type

asm file icon: asm filetype icon

The asm file extension is associated with programs written in assembly language, a low level programming language, which can be converted to another machine language.

The asm files can be be edited with a text editor and run using an assembler program, such as HLA, MASM, FASM, NASM, or GAS.

Typically a modern assembler creates object code by translating assembly instruction mnemonics into opcodes, and by resolving symbolic names for memory locations and other entities. The use of symbolic references is a key feature of assemblers, saving tedious calculations and manual address updates after program modifications. Most assemblers also include macro facilities for performing textual substitution—e.g., to generate common short sequences of instructions to run inline, instead of in a subroutine.

Assemblers are generally simpler to write than compilers for high-level languages, and have been available since the 1950s. Modern assemblers, especially for RISC based architectures, such as MIPS, Sun SPARC and HP PA-RISC, optimize instruction scheduling to exploit the CPU pipeline efficiently.

Since assembly code is typically more difficult to write than C or C++ code, the asm files are often combined with other C or C++ script files, which will handle the majority of the application logic.

Help how to open ASM files:

You can open and edit the ASM file using any suitable text editor or specialized programming software tool.

How to convert file with extension ASM:

As far as we know, this .asm file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
