Linear Executable is an executable file format in the EXE family. It was used by 32-bit OS/2, by some DOS extenders, and by Microsoft Windows VxD files. It is an extension of MS-DOS EXE, and a successor to NE (New Executable).
There are two main varieties of it: LX (32-bit), and LE (mixed 16/32-bit).
A Linear Executable file begins with the ASCII signature "
MZ". At offset 60 is a 4-byte integer pointing to an "extended" header that begins with "
LX" or "
LE". For more information, see MS-DOS EXE.
