W32DASM is a program for Windows intended to serve as a disassembler. In other words, the application is capable of translating machine language back into assembly language. This is a convenient solution for people interested in reverse engineering, who want to take code apart and discover how it works.

Formats and functions

The software can process a considerable number of extensions, including EXE, 386, COM, CPL, DLL, OCX and others. Thus, you have the ability to save the disassembly text and create project files. Similar to IDA, it is possible to attach the active 32-bit process to the debugger, and load the deconstructed executable into the process.

What is more, you are able to use a text search function, configure the disassembly listing at the current instruction pointer, as well as toggle break DLLs on load and unload. You also have the option to browse the alphabetical index of imported and exported functions, find string data, or directly examine objects and segments via hexadecimal display.

Performance

Even though the program has not received updates for a long time, as it is discontinued, it works without any issues on modern Windows editions. Items are disassembled quickly and the utility remains light on system resources consumption.
