"MZ" means?
MZ
(standard, file format) The file signature of an MS-DOS executable (.EXE) file (0x4d 5a), always the first two bytes of the

file. It was reportedly invented by, and named after, a Microsoft programmer, Mark Zbikowski. In Unix systems, the string MZ

is the magic number that identifies an MS-DOS EXE file. (2003-06-10)

?This is Behind the Code’s pilot episode with Core File Services architect, Mark Zbikowski. Mark began his career at

Microsoft in 1981, working on DOS 1.0 as a designer, coder and liaison with IBM. His quarter century long career has included

significant involvement in OS/2, Cairo’s Object File System (OFS), and the NT File System (NTFS). In addition, he has been a

key player in all of Microsoft’s File System work. Former Microsoft software architect Pat Helland interviews Mark about the

early days at Microsoft, his passion for product development and the challenges of producing software.
