What is an *.MDS file?

I downloaded a movie which comes as a *.mdf file(630Mb) and a small *.mds file (1Kb). How can I watch the movie on my computer?


The MDF file is a CD image file, and MDS is the corresponding catalog file. Software such as 'Alcohol 120%' reads this catalog file so that it knows how to burn the MDF file. You can play the movie directly from the burned CD. Download the trial version of Alcohol 120% from their web for free:

If you do not want to burn the image file on a CDROM (maybe you have no burner or no blank CD handy) then you can download a tool like IsoBuster or WinISO, open the image file and extract the contents to desired location on your hard disk.

You may even use the above mentioned 'Alcohol 120%' and have it create a virtual drive for you, then you can simply right-click any cd-image file you have and 'mount' it. That makes it as though it were a burned image- you can play, extract, install, whatever you want.

this is all very interesting but how do you burn the ISO image and the MDS file to the same disk? is it a GUI? An auto run.exe? how do I combine the 2 so I can burn them at the same time. I use image burn and have been very satisfied with it. I downloaded a free copy of alcohol but it was infected so I a little gun shy. Feedback?

Well I went to another page and found out straight away that I don't need the file. It's just a meta file with a little info on it. My ISO should work fine.Not one person master or n00b mentioned that little tidbit. Semi- n00b

You can open these files using WinRar and just unzip them.

thank you so much for this helpful post :) i'm used to handling .iso files with Alcohol 120%, so this time around when the program didn't work for me for some reason, ISOBuster did the job :)
