Assembler Source Code Format | N/A | Developer Files |
The ASM file extension is used for an Assembler Source Code file written in Assembler language. This type of file contains instructions written using the assembly language that create a mapping between the instructions set of a particular processor and the operations on the data. It is not meaningful to human readers but it is directly understandable to the processors. ASM files are created for use with the Macro Assembler. This tool is designed to take ASM coded instructions and convert them into an executable code for the computer’s CPU (Central Processing Unit).
Detailed Description
ASM files are usually used when it is necessary to optimize the instructions running process for a certain application. Since this programming language has powerful primitive commands, many complex operations can be performed quickly and efficiently by using this type of file. It makes the applications compile and run faster than with other languages. When compiled, these files may have an .OBJ, .COM, or .EXE extension.
Though not as popular as other programming language files, ASM is often used by developers in game development, drivers, etc. Usually we find this source code file used in tandem with C/C++, Java and other programing languages as well. Similar file extensions include: .ASM, .S, NASM, .IL, and FASM.
Programs for WINDOWS system
Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .ASM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .ASM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .ASM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .ASM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .ASM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .ASM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .ASM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .ASM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .ASM file) will be extended to the maximum.
It is also good to check
- if the .ASM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
