BackUp file doesn't open

[Stelios_2]

I made a backup file and when I try to open it and I see this https://imgur.com/5MUiGA7
What can I do?
I have windows 10

That is not really a backup file, that is a disk image which is a snapshot of the disk as a whole. What program did you use to make the image file and what are you trying to do with it?
