New Executable ( English executable for executable ') is a 16-bit - file format for executable files under Microsoft operating systems, which as a successor to the MZ format applies. It was used in 16-bit Windows operating systems , the multitasking system MS-DOS 4.0 , OS / 2 1.x, and in the OS / 2 subsystem from Windows NT up to version 5.0 ( Windows 2000 ).
The successor is the portable executable format for 32-bit and 64-bit versions of Windows.
compatibility
For reasons of compatibility, programs in the New Executable format begin with the header of an MZ file , which is executed when the program is called under DOS . For most programs, however, this contains nothing more than the output of an error message, the so-called “DOS stub ” - the output reads “ This program cannot be run in DOS mode ” . However, complete fat binaries for DOS and Windows are also available . H. with a full DOS and Windows version of the program. From this possibility z. B. the setup program ( ) of Windows 3.1 use.
SETUP.EXE
Although primarily developed for 16-bit Windows operating systems, files in the New Executable format can also be executed under 32-bit Windows. Operating systems from Windows Vista can no longer display icons from New Executable files.
16-bit programs cannot be executed on 64-bit Windows systems. NE files are still in use on all Windows systems, since bitmap fonts ( .fon
) are technically NE files, although they do not contain any executable code.
