Think of it this way: You can write a recipe (BAT) and then bake a cake (EXE). But you cannot fully reverse-engineer the cake back into the exact original recipe, only approximate ingredients.

Suppose you have a program named backup.exe and you want it to run silently in the background.

: A utility found on GitHub designed to wrap command-line applications into batch scripts to simplify analysis or customization.

A (Batch) file is a plain text script. It contains a series of commands that are interpreted by the Windows Command Prompt (cmd.exe) line by line. It is essentially a way to automate tasks you would otherwise type into the terminal manually.

| Goal | Solution | |------|----------| | Run EXE from batch | Create a .bat that calls the .exe | | Automate EXE tasks | Use batch to pass arguments, check errors, loop runs | | Reverse‑engineer EXE | Use decompilers (ILSpy for .NET, Ghidra for native) – | | Recreate simple tool | Write a new .bat script from scratch with same purpose |
