A rare computer user has not come across archives and virtual disks. The formats "zip", "rar", "iso" are familiar archive extensions. However, there is such an archive format as "mdx", which can cause some difficulties when opening.
What is the format
There are two cases in which the "mdx" format can be used:
- used as disk image containing information (audio, video, games, etc.);
- in rare cases, is database index.
Let's move on to the first case.
MDX is a combination of previously used files "mdf' and 'mds» . The first one stored files, and the second one - information about the disk. These archives were used to distribute information on disks, USB drives, or on the Internet.
The scope of MDX is different, but the main direction is data storage from CDs or DVDs.
Trouble opening may arise due to incorrect creation or incomplete downloading from the Internet.
Programs to open
Daemon Tools
One of the most popular programs for working with disks and their images. There are two versions of the Daemon Tools program: Lite is free and Ultra- paid, but with a trial period of 14 days.
You can open the mdx file in Daemon Tools only version 4.35 and above in Windows 7, 8, 10.
The interface looks like this: 
To open you need:
This program has on "its board" sufficient functionality for mounting virtual disks various formats, including the MDX format.

Instructions for opening the mdx extension in Windows 7, 8, 10:
This will open the autorun window.
Next in line is another program designed to work with disks (including those with the mdx extension). is shareware program (with a trial period).

How to convert mdx to iso
ISO images are much more common, and unlike MDX, they can be opened even by ordinary archivers. If there is a need to convert "MDX" to "ISO", you can do this in any of the above programs. The following describes how to convert to UltraISO programs and DaemonTools.
One of the controversial formats is ".mdx". It, like some other specific formats, has several purposes at once that contradict each other.
Let's try to figure out how to open an mdx file on a computer.
Why is the format used?
The main and most common use case is considered to be the use as a format for creating disk images. One could even argue that ".mdx" is an alternative to using a bunch of "mds" and "mdf" formats.
That is, "mdx" combines information about the disk image and its structure, as well as the disk files themselves. It turns out that such a data type is inherently as close as possible to "iso", which contains a similar specification.
Main purpose
The primary idea was to create a document that would combine a file archive of information recorded from a disk with a register containing information about access to this archive. After separating the use of files for these two purposes, the approach turned out to be a breakthrough.
Note: despite the "breakthrough", a similar approach before the advent of "mdx" was used by competitive programs. Therefore, the appearance of a data type should rather be considered a recognition of the effectiveness of such a decision.
Additional appointment
Another meaning of the word MDX in the world of computer technology is the definition of Multidimensional Expression - a database language similar in appearance and structure.
The key role in this is played by the absence of files in the specified format. The language and disk images are not related to each other, so we will not return to the issue of the MDX language.
Image Assignment
Approximately 10 years ago, the creation of images was more of a pirate character. Based on the image, versions with remote protection were produced, which were sold at a reduced cost. As time passed, the developers also paid attention to the format.
If a game or program is distributed via the Internet (via online purchase), then the user may not wait for the disc, but download it directly through global network. On the other hand, some developers have abandoned the image system and offer to use online installers.
With the help of the "mdx" file, that is, by creating a disk image, you can achieve the following results:
- to simplify the transfer of information via the Internet;
- save the disk itself using its key on the image (this is not piracy, since the user purchased the key and disk);
- ensure the transfer of a large number of copies installation disk, saving on records;
- save multiple images in one for later use.
For the above reasons, the distribution of images plays an important role in IT communications.
Opening methods
Since the main purpose of the format is to use for images, it is logical that programs designed to work with images will open it.
Example "Imaging tool Windows drives” will be omitted, since 2 factors immediately testify against this program:
- The optimal configuration and operability for writing images was made only in Windows. In previous versions of the OS, they are often not able to read a disk that was burned with their help a few minutes ago.
- The virtual drive creation factor appeared only in Windows1 and needed to be improved.
Overall, missing out on the built-in windows tool, I had to focus on such requirements as: creating new and editing existing virtual copies of disks. On the other hand, if the creation tool is typical for all the applications described below, then full editing is available only in one of them.
Daemon Tools
One of the most popular tools for working with disks, virtualization and recording virtual copies. The word virtualization should be understood as copying files from media to HDD for the purpose of their further use as virtual media in virtual drives.
Despite the complexity of the explanation, the DT algorithm is based on the following principles:
- The program creates a copy of the disk with the appropriate extension - mdx or a pair of mds + mdf files.
- The tools daemon also allows you to create virtual drives, which essentially perform the same function as a computer's CD-DVD drive.
- Mounting or connecting an image file to such a drive is considered the simplest virtualization.
It is thanks to the existence of Daemon Tools that the mdx document extension saw the light of day. This program responsible for working with such images and their creation.
Alcohol 120
Alternative option with a similar set of properties. It helps you create images, write to disk from an image, mount virtual drives, and make full use of virtual media.
Separately, we should dwell on the recording algorithm, which was later added in the same way to DT. The image is mounted according to the principle described above, and then standard means system is copying from one drive to another.
The principle is simple, but quite effective, and similar programs have picked it up.
Ultra ISO
Stands out for one key feature: in addition to all the above functions in this program, the ability to edit images has been added. That is, remove the unnecessary part of the materials or add what seems necessary.
This program has a trial period of 30 days, but is the most expensive among its peers. On the other hand, it makes no sense to consider the applications named above as full-fledged competitors for UltraISO.
Initially, the purpose of this product was to edit previously created files. Now it performs all the same functions as its competitors and works with the same formats.
It has a separate plugin that allows you to open and view mdx documents without too much trouble. Such a file can be unpacked with the help of the TS and used like an archive.
If the information you need was in the form of a file in an unfamiliar MDX format - don't be afraid. It's just one of the disk image formats. These files contain all the information recorded on CD/DVD/HD DVD/Blu-ray disks. The image can be stored on the computer's hard drive, according to it special programs created virtual disk — i.e. simulates the presence of physical media in the drive. This significantly speeds up and facilitates the work with information - music, games, applications, data - recorded on disk media. Thanks to the image files, in order to use the information from the disk, you do not need to insert it into the drive every time, but just run a virtual copy.
How to open mdx file? This can be done using applications that support disk imaging.
Necessary:
- a program installed on the computer DAEMON Tools or alcohol.
Instruction:
- Run the program DAEMON Tools. Her version should be 4.35.6 or higher. Files in the format MDX just created in it, so open their With her help, it's not difficult. Create a virtual disk based on the image file and run it to see the data stored in it. Program DAEMON Tools free for non-commercial use and can be downloaded online. It allows you to create up to four virtual drives.
- Another popular disc image recognition software is alcohol. This program makes exact copies of disk media, supports up to 31 virtual drives. Series programs alcohol support most image formats, including the ability to open mdx.
If your computer has antivirus program Can scan all files on the computer, as well as each file individually. You can scan any file by clicking right click by clicking on the file and selecting the appropriate option to perform a virus scan on the file.
For example, in this figure, file my-file.mdx, then you need to right-click on this file, and in the file menu select the option "scan with AVG". When choosing given parameter will open AVG Antivirus which will check given file for the presence of viruses.
Sometimes an error can result from incorrect installation software , which may be due to a problem that occurred during the installation process. It may interfere with your operating system associate your MDX file with the correct application software tool , influencing the so-called "file extension associations".
Sometimes simple reinstalling DAEMON Tools may solve your problem by properly linking MDX with DAEMON Tools. In other cases, file association problems may result from bad software programming developer, and you may need to contact the developer for additional help.
Advice: Try updating DAEMON Tools to the latest version to make sure you have the latest fixes and updates.
This may seem too obvious, but often the MDX file itself may be causing the problem. If you received a file via an attachment Email or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may be corrupted. If possible, try getting a fresh copy of the MDX file and try opening it again.
Carefully: A corrupted file may cause collateral damage to a previous or existing malware on your PC, so it is very important that you have an up-to-date antivirus running on your computer at all times.
If your MDX file associated with the hardware on your computer to open the file you may need update device drivers associated with this equipment.
This problem usually associated with types multimedia files , which depend on the successful opening of the hardware inside the computer, for example, sound card or video cards. For example, if you are trying to open an audio file but cannot open it, you may need to update sound card drivers.
Advice: If when you try to open an MDX file you get .SYS file related error message, the problem could probably be associated with damage or outdated drivers devices that need to be updated. This process can be alleviated by using driver update software such as DriverDoc.
If the steps didn't solve the problem and you are still having problems opening MDX files, this may be due to lack of available system resources. Some versions of MDX files may require a significant amount of resources (eg. memory/RAM, processing power) to open properly on your computer. This problem occurs quite often if you are using a fairly old computer. Hardware and at the same time a much newer operating system.
This problem can occur when the computer is having a hard time completing a task because operating system(and other services running in background) can consume too many resources to open MDX file. Try closing all applications on your PC before opening Extended Media Descriptor File. By freeing up all available resources on your computer, you will ensure the best conditions for trying to open the MDX file.
If you completed all the above steps and your MDX file still won't open, you may need to run hardware upgrade. In most cases, even with older hardware versions, the processing power can still be more than enough for most user applications (unless you're doing a lot of CPU-intensive work like 3D rendering, financial/science modeling, or intense media work) . Thus, it is likely that your computer does not have enough memory(more commonly referred to as "RAM", or RAM) to perform the file open task.
mdx format files are the next generation of mdf files. Both of them are designed to work with disk images. In fact, these are the images themselves. What is the difference between mdx and mdf? And the difference is that now the disk image contains only one file, which stores all information about the image. mdf file also needed the mds file where the part was located necessary information. Therefore, we see that mdx is a more convenient and economical model for disk images. How to open mdx?
Special programs
Alcohol 52% is one of the most popular CD/DVD drive emulation applications. You can download Alcohol 52% from this link: Alcohol 52%.exe (12.8 Mb). The program will allow you to create the most accurate copies of discs and load them onto virtual media without any problems. You have the option to install up to 31 drives. These drives are capable of running disks at speeds up to 200x. Alcohol 120% supports most disk image formats, including mdx. If you need to constantly work with discs, that is, put them in and take them out, then Alcohol 120% - The best decision. You will not need to force your drive to constantly open it, since all the images of the necessary disks will be stored in the main memory of the computer.
More simple version for reading virtual disks are programs of the Daemon Tools series. The main advantages of the program are its convenience, speed and availability. Download latest version programs can be completely free at this link: DAEMON Tools Lite.exe (11.2 Mb). The program is installed in the system as a virtual drive and is designed for 4 disks, which, of course, is not much compared to the emulator from the developers of Alcohol. On the other hand, Daemon Tools does not require a lot of computer memory resources. The program also works with a large number of formats, including mdx format images.
The programs listed above are designed for ease of use on personal computers. The situation in the world of computer and multi-media business develops in such a way that these applications are used for illegal copying of information from licensed media. In no case do not succumb to the provocations of pirates. Remember - intellectual property costs a lot of money, so for its unauthorized distribution, you can pay a huge fine or even go to jail for quite a long time. Use the programs only for personal purposes and do not try to profit from them. It is illegal.
