Once extracted, you will likely find an .mp4 , .mkv , or .iso file. You can then use a media player like VLC to view it or check the file properties for more information.
Ensure you have all preceding parts ( part01.rar through part27.rar ) in the same folder.
Right-click on DODIFHV.part01.rar and select "Extract Here." The software will automatically pull data from the other 27+ parts to rebuild the original file.
