If you need to edit the GDN file, one of the safest methods is to download and install the software dedicated to working with GDN files. There are many tools known as GDN Online Editors, but it is not certain that they operate in a way that keeps the data contained in the file safe.
The installation of the program that supports the GDN file does not guarantee that the file can be edited. Additional information about the GDN file extension can be found here.
This is the best way. Choose one of the programs that support the GDN file extension, open your file and check the editing options. It's safest to download the software from the developer's website. Links to the websites of software producers can be found on the software subpages. Below you will find some examples of software programs that support the GDN file (so it is very possible that they can edit files in GDN format).
The full list of GDN supporters
Remember that many file types have a text format and you can preview their contents by opening them, for example, with Windows Notepad. However, such manual editing of the GDN file or any other file may result in damage to the file. After saving the changes, it may not be possible to reopen the GDN file. For this reason, try to use software created to edit GDN files.
It seems that one of the software on the list must be able to edit the GDN files. Use other options if you still haven't found a way to edit GDN. Below are tools that allow you to edit GDN online files.
