Offset Size Description; 00H 2 Signature Word.This contains a 'magic number' which provides a simple check that the file really is a DOS .EXE file; it follows that the filename extension does not in fact have to be .EXE, as long as programs check this word.The value of this word is 5A4DH (with the 4DH coming first). word reloc_count IMAGE_MZ_HEADER::HTPACKED Definition at line 34 of file mzstruct.h.

This header remains largely undocumented, however, so examining it at length is unlikely to yield any insightful information. To remain compatible with previous versions of the MS-DOS and Windows, the PE file format retains the old MZ header from MS-DOS. For simple (16 bit) MSDOS software, this ought to be 0, and for any extended format it should point right to one of the specific LE, PE, or NE headers' identifiers (which all are exactly those two characters).

In that window you can set also whether the header should be added below the declaration for items that have body. from customizable templates that can use predefined variables (whose value is assigned automatically by MZ-Tools, such as file name, method name, author, etc.) The MZ DOS executable file is newer than the COM executable format and differs from it. MZ. Finally, following the DOS and rich headers comes the PE header marked by “PE..”, or the byte sequence x50x45x00x00 which indicates that this file is a PE32 executable.
