How to Open DAA, VCD, NRG, IMG, MDF Files

DAA The abbreviation DAA stands for Direct Access Archive. Files with the extension .daa contain files with the images recorded on CD/DVD. Files in the DAA format are associated with the PowerISO file processing tool.

Files with the extension .daa have additional functionality, such as password protection, file compression, file splitting, etc. With this format, you can compress media files, which makes it easy to download movies and music from the Internet and store them.

Users can copy DVD and CD discs to DAA format files, which allow them to play media items on their computer without using such discs.

What program you should use to open these files:

  • PowerISO
  • Magic ISO Maker
  • MagicDisc
  • FastFox

Also, you can read about other programs and download them on WikiExt.


VCD (Video CD) – format for recording video and audio on CDs. Such disks can contain relatively high-quality video of a small size. Since a CD can hold up to 800 MB of video, then at high quality, the video will be very short. This video can be recorded using many programs, such as Nero, and you can view VCD on almost any CD player. As for watching VCD on a computer, you can use one of the players built into this set: GOM Media Player, Total Video Player, ALLPlayer, RealPlayer, SMPlayer, Haihaisoft Universal Player, The Core Media Player.

All players have good functionality and support many video formats. After inserting the VCD CD into the drive, go to the Explorer and open the video in the player you need.

When choosing a player, you need to manage several factors. The first is the appearance and intuitive interface. The second is the ability to adjust video quality. Third – individual characteristics, such as the possibility of multiple amplification of sound, work with subtitles, etc.


NRG is the disk image format that was created by Nero. This format is especially good for creating CD images. Images are often used to backup data, and create copies of disks.

Based on the functionality of programs that support this format, you can perform the following operations:

  • write NRG images to disk;
  • create such images;
  • edit, convert NRG to other formats;
  • encrypt and compress images;
  • mount NRG images;

Disk images are not just a copy of the data contained on any removable media, but also a copy of the data structure that indicates the format and storage of the data. To create virtual images, you need to use one of the programs listed below. If you want to copy an image from a medium, then this procedure will not be difficult – usually, you need to do just a few mouse clicks. Editing images can be time consuming, although this operation will not require you to have special skills. The user can add and delete folders, change files in the image, change their names, etc.

You can open this file using such programs:


IMG is used to create disk images that can be mounted as a virtual disk (as an external hard disk) or as a virtual optical disk (CD or DVD). In order to work with files of this format, it is necessary to find an acceptable program that supports this format of images. After installing the program, you can mount the image and access the files inside it. Some of the programs suggested in the list below can also create IMG images that contain the files you have added.

UltraISO, as one of the most popular tools for working with images, is able to read and create more than 40 image formats, including IMG. The program is very popular for several reasons. First, UltraISO has an excellent set of functions for creating and editing already existing images. You can just open the image and replace the files in it. Secondly, with the support of such a large number of formats, the program has no limitations.

To view the contents of the IMG image (but not for editing), you can use IZArc, a free archiver that can unpack the images into a folder. After unpacking the image, you can open any files from it, just like when you mount a virtual disk. In other words, unpacking the image can completely replace the mount operation, the only problem is that after the image is dismounted, there will not be any extra files left on the hard disk, and in the case of unpacking all the folders and files will need to be deleted after using them. Other programs that you can use:


Files with the .mdf extension are images of CDs and DVDs stored in one file on the computer. Typically, for the correct operation of these images, the MDS file containing the service information is also saved – however, if this file does not exist, we will open the file without it.

There are many programs that you can download for free and which allow you to open files in the MDF format. It is worth noting that the “opening” of these files does not quite happen as the opening of other types of files: when you open a disk image, it is mounted in the system, you seem to have a new drive for reading CDs on a computer or laptop, where a disc recorded in MDF is inserted.

Here are some programs that will help you open a file with MDF extension:

  • Daemon Tools
  • Alcohol 120%
  • Cyberlink PowerDVD
  • IsoBuster
  • MagicISO
  • Virtual CloneDrive
