How to open a .DFN file?
If you have problems opening the file DFN, then in most cases the problem is only the lack of the proper application installed. Select one of the programs from the list and install it on your device. The operating system should automatically associate the DFN file format with the installed program. If not, right click on your DFN file and select from the menu "Open with" . Then select the installed program and confirm the operation. Now all DFN files should automatically open with the selected program.
