If you cannot open the D4 file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable application that supports D4 among those that are installed on your computer.
A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the D4 file can be found below. Now just download and install the appropriate application.
This site also defines other possible causes causing the problems with D4 files.
The inability to open and operate the D4 file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the Dataphor Source file. Below is a list of possible problems.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the D4 file should operate with your programs without any problem. If the problem with the D4 file has not been solved, it may be due to the fact that in this case there is also another rare problem with the D4 file. In this case, the only you can do is to ask for assistance of a professional staff.

If you want to associate a file with a new program (e.g. my-file.D4) you have two ways to do it. The first and the easiest one is to right-click on the selected D4 file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK.
Many files contain data in the form of text or numbers. It is possible that while opening unknown files (e.g. D4) a popular Windows simple text editor, which is Notebook will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
