How to Convert Your MDS Files to ISO

If you use optical disks a lot, you might have come across a file that has a .mds extension. It’s a disk image of some data that cannot be accessed by double-clicking or pressing the enter button. Special related software has to be downloaded and installed for you to interact with the files on the disk image. Most of us overcome this hurdle by converting the file to a different format. The most preferred format for converting to is ISO. Let’s take a look at the reasons behind the mass appeal and analyze some of the solutions for conversion.

What is MDS?

It is a media descriptor file generated when you create a CD/DVD image. It describes the original information on a disk image layer breaches, and it is mostly used as a copyright tool for the disk image.

How do you open MDS files?

MDS files require special software to open, luckily, they are many applications that are designed for this specific task. Most of us tend to use Alcohol 120%, but MagicISO and UltraISO work just as well.

Are MDS files secure?

Considering the other data they contain other than the stored files, they tend to be secure. The copyright protection features and disk track data have proved useful in regards to data security.

By how much will it set me back?

It will cost you nothing, my friend. Most conversion software is free to download. And trust me, they work.

2 Ways to Convert MDS files to ISO

I bet you’re getting convinced about converting to .iso. Now let me share some solutions on the conversion process.

1. Use software

Conversion software exists for both Mac OS X and Windows. Some are paid while most are free, and the difference between the two is tiny. Mac fans generally use MISO-J which supports multiple formats and is regarded as a file utility software. Windows users have quite a range to choose from. PowerIso, Ultra Iso and ISOBuster are just a few. Not much is known about Linux compatibility, but I’m sure they have some.

The great thing about this software is that you’re not just limited to converting to ISO. A host of other formats are available.

Once you’ve selected your preferred software, you proceed to download, install and run it on your pc.


You then select the MDS file destined for conversion. Then from the file manager, open the file to view to contents of the disk image. Click on the file button and select save as. Enter a suitable name for the file and select the .iso extension. You can then save the ISO file to a folder of your choice.

2. Change the file extension

This method has proven useful before when converting other formats to .iso. Files such as EBOOT.PBP can be converted by renaming the file and changing its file extension to .iso. This method is, however, unlikely to work for large complex files. There is a good chance that the resulting file will be unstable. What do you think? Would you try it out on your MDS files?

What I’d choose?

I dread entirely losing any of my files or having them become inaccessible. I would go for the tried and tested method of using conversion software. And why not? Most of the best ones are free to download and use.


For those who value data integrity, having multiple back-ups of your data is very important. It ensures you never have to start from scratch in case of data loss. Whether through device damage or transfer malfunctions. Some go the extra mile and convert the data to different formats so it can be stored and accessed on an assortment of devices. As technology continues to progress towards the digital sphere, we might as well keep up with it. I convert most of my important data, to maintain access to it after the original models get phased out.
