EXE is an extension of the name of Microsoft Windows, MS-DOS, and OS/2 executable file systems; files with this extension are primarily intended for storing compiled program machine code, although they may also contain other resources (for example, related to the structure of windows, icons, images, sounds, etc.).
A file signature is a sequence of bytes, usually at the beginning of a file, that helps determine the file format (this is another confirmation element after the file extension); in the case of EXE executable files (and other files with identical structures, including DLL, OCX, ACM, AX, IME, MUI, RLL, TSP, CPL, DRV, VXD, SCR and some SYS) the first two characters are usually the letters "MZ" comes from the initials of the author, Marek Zbikowski. The EXE file can contain executable code in various formats, binary files of the Portable Executable type later contain the "PE" signature.
Formats
There are several basic executable file formats :
DOS
A 16-bit DOS executable file in the MZ format is the source file of a DOS executable file identified by two ASCII characters "MZ" at the beginning of the file; it has relatively few features. "ZM" signs are also allowed, but are used much less frequently.
16-bit (New Executable) – used in multithreaded versions of DOS 4.0 and 16-bit versions of Microsoft Windows, indicated by the letters "NE" at the beginning of the file; it did not gain much popularity, it could not work in other versions of DOS, but it was possible with 32-bit versions of Windows and OS / 2 .
In the case of executable files in 16- and 32-bit format for Windows, it is standard to run them from a short program preceded by the signature "MZ" (the so-called stub). Its purpose is usually to inform about the purpose of this program for Windows (usually in the form of the text "This program cannot be run in DOS mode". ( Pol. "This program cannot be run in DOS mode"). Or "This program requires Microsoft. Windows. " Although you can include other code here (using the appropriate linker parameter), for example, the DOS version of the program. The main part of the program, that is, the fragment intended for Windows, has the signature "NE" or "PE" – the code starting with the signature "MZ" is ignored (except for the reference to the PE structure and the signature itself). However, "PE" code can also be executed in DOS using the DOS HX expander mentioned above.
