There are times when you only need to display the contents of the D1 file. Then do not install dedicated software and use tools such as D1 Viewer. This type of tool is nothing more than a program or an online application that allows you to easily view the content of the data stored in the D1 file. You have several options to view the contents of the D1 file:
If our D1 Viewer Online did not help you, you have a few more options. One of them is to use software that works with the D1 file. Here are some sample programs that can help you. By choosing the option to install dedicated software, you will also be able to e.g. edit the D1 file and sometimes even convert the D1 file.
The first important thing is that you will need to download and install a dedicated application that supports the D1 format on your device. In this case, it is not possible to view the D1 file online. Here you will need more time to use this solution, but you will also have more options. You can find some examples of dedicated software below, and the full list is here D1 File Opener
If you haven't been able to preview the contents of the D1 file yet, or you don't want to install any dedicated programming to handle these files, you can try something else. Many file types are simply text files or data archives. In this case, you can try to open your D1 file with the simplest text editor, for example with "Notepad". This solution does not guarantee that the problem will be solved, but it will often allow you to view the data in the D1 file to some extent.
The second way is to use a data archiving program. Try to open your file with e.g. Winrar or Winzip. If our theory proves to be correct, you should see the tree of files contained in the archive. To get information about what kind of data it is, go to the subpage with information about the D1 file extension.
