How do you mount files marked .daa?

[Kraise]

I just finnished torrenting a game called The Elder Scrolls 14 : Oblivion, and the files that are used to install the game are .daa's , and these are files that show on d-tools to be unsupported, or not listed. I tried just mounting them anyway, but it does not start. Do i need to download one of the addons for this? or do I need to simply find some other program?

Will not mount daa files?

I tried to mount a .daa file for a game i'm trying to get installed, but it wont mount, nor is it on the list, it is a dvd, but i wouldn't think that'd have a problem in this
