mdf and mds mounting bullshit

alright so I got 4 different cd folders, (basically 4 CDs)
each folder has an mdf and an mds

Now I've been told im supposed to use alcohol 120 to mount these files but my trial ran out and before the trial I had problems with it, I tried cracking it but heey lucky me it was an undetected virus, so now I just got rid of it and I dont even want to fucking bother with fucking alcohol 120 anymore

is there any other program I can use to mount these files, and how?

daemon tools

yeah I had used v. 3.4 and it didnt work, I just had to get the new version.

thanks
