What is the .LE File Extension?

.LE File Extension Description:

The file extension LE identifies an executable image file generated by the application DOS/4GW PM32x.

The file with the .le file extension serves as DOS extender and is opened on the command prompt. It works as a 'virtual disk' and takes on the features and functions of a disk drive. It is basically a variation on file compression, like ZIP or RAR files.

When running the DOS/4GW application on 32-bit platform, the file with the .le file extension is used to implement the executable image. Many programmers and administrators prefer executable images over images that are non-executable when using the DOS/4GW program. This is because executable images contained in the file with the .le file extension, if suitably created, are more flexible and can handle upgrades in the operating system.

The LE file extension containing the executable image conforms to the mapping mechanism of the DOS/4GW PM as a DOS extender. This allows it to read read-only files and system sections. It also makes itself shareable, especially in multiple-user environment. The shareable portions of the file with the .le file extension can be mapped into memory at one time only.

The file with the .le file extension also has the advantage of fast loading and flexibility, making it easier to distribute into memory. This is unlike the non-executable image that distributes itself as "kernel" and will not run unless all data is mapped into memory.

Executable images are commonly used on Linux and Macintosh operating system. Many program installers make use of executable images because it can be easily distributed into memory. On the other hand, Windows uses less executable images and only implements it when contained in DOS/4GW to function as DOS extender.

The file with the .le file extension containing an executable image is called when the operating system implements virtual memory data structures. Consequently, it contains and implements page tables and acts like virtual disk that administers its own memory.
