opening file .bdu

[Zekfly]

Hi, I need to open an old file that has a type extension
*.bdu_******, opening it with a text editor in the first rows shows the word euclid that makes me think that was the cad with which it was made. I tried to search the internet for the bdu extension but I didn't find anything... Can anyone help me? thanks in advance
