Linear Executable
Linear Executable (LE) is file format for executable code designed for 32-bit protected mode operating systems. Originally used by the OS/2 operating system and adopted by various DOS extenders, it also served as the file format for Virtual Device Drivers (VxD) in early versions of Windows, including Windows 3.x and the Windows 9x series. The malleability of LE files attracted interest in using them for steganography.
