Canon 5DMIII How to access mlv files?

[MrGuyDude]

Okay! So I get that this is a total newbie question, but that's exactly what I am.
I activated 14bit RAW in 1920x1080, but except for the replay function I just simply don't have access to my recorded footage.
It clearly tells me that it saves A:/DCIM/M27-1251/M27-1254.MLV: 1920x1080, but where is it? How can I get it?
I'm clueless!
Please help!
