What is the .DDP File Extension?

.DDP File Extension Description:

The DDP in the DDP file extension may have several meanings. One, it may be the Dinkey Dongle Protection; two, it may be a Delphi Diagram Portfolio, and three; it may be a device driver profile.

The function of the DDP file extension as the protection parameter for the Dinkey Dongles is very important. This application functions by preventing the illegal production and copying of software, by locking the software into its hardware key that is plugged into a USB port of a certain computer. The DDP file extension is important since it defines the protection parameters set by the Dinkey Dongle for the software to be protected.

It also helps in applying the full potential of the Dinkey Dongle features, like its numerous encryption and anti-debug methods, and its control for the number of times that the software can be executed. Other features include its compatibility with various platforms like the Microsoft Windows, Mac OS X, and Linux.

Meanwhile, the DDP file extension works as the device driver profile for the OS/2. This is a computer operating system that was introduced for the second-generation personal computers. The DDP file extension allows the OS/2 to interact with different devices that were installed in the computer system. The DDP file extension works by communicating with the hardware devices through the use of computer bus, or other communication subsystem where the hardware device is connected.

Whenever the hardware device is needed, a program calls the hardware and the DDP file extension issues specific commands for the device. If the device sends back information to the DDP file extension, it may then call for a routine. Since most drivers are operating-system specific, the DDP file extension may be found working only with the OS/2 operating system.

Also, the DDP file extension can be found as diagram portfolio for the various Delphi applications of Borland Software Corporation. Some may also find this as a software file for the Inor DSoft.
