If you have installed on your computer antivirus program Can scan all files on your computer, as well as each file individually. You can scan any file by right-clicking on the file and selecting the appropriate option to scan the file for viruses.
For example, in this figure it is highlighted file my-file.img, then you need to right-click on this file and select the option in the file menu "scan with AVG". When you select this option, AVG Antivirus will open and scan the file for viruses.
Sometimes an error may occur as a result incorrect software installation, which may be due to a problem encountered during the installation process. This may interfere with your operating system link your IMG file to the correct application software, influencing the so-called "file extension associations".
Sometimes simple reinstalling IsoBuster may solve your problem by linking IMG to IsoBuster correctly. In other cases, problems with file associations may result from bad software programming developer and you may need to contact the developer for further assistance.
Advice: Try updating IsoBuster to the latest version to ensure you have the latest patches and updates.
This may seem too obvious, but often The IMG file itself may be causing the problem. If you received a file via an email attachment or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may become damaged. If possible, try getting a new copy of the IMG file and try opening it again.
Carefully: A damaged file can cause collateral damage to previous or existing malware on your PC, so it is important to keep your computer up-to-date with an up-to-date antivirus.
If your IMG file related to the hardware on your computer to open the file you may need update device drivers associated with this equipment.
This problem usually associated with media file types, which depend on successfully opening the hardware inside the computer, e.g. sound card or video card. 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try to open an IMG file you receive .SYS file error message, the problem could probably be associated with corrupted or outdated device drivers that need to be updated. This process can be made easier by using driver update software such as DriverDoc.
If the steps do not solve the problem and you are still having problems opening IMG files, this may be due to lack of available system resources. Some versions of IMG files may require a significant amount of resources (e.g. memory/RAM, processing power) to properly open on your computer. This problem is quite common if you are using fairly old computer hardware and at the same time a much newer operating system.
This problem can occur when the computer is having trouble keeping up with a task because the operating system (and other services running in the background) may consume too many resources to open the IMG file. Try closing all applications on your PC before opening Disk Image Data File. Freeing up all available resources on your computer will provide the best conditions for attempting to open the IMG file.
If you completed all the steps described above and your IMG file still won't open, you may need to run equipment update. In most cases, even when using older versions of hardware, the processing power can still be more than sufficient for most user applications (unless you're doing a lot of CPU-intensive work, such as 3D rendering, financial/scientific modeling, or intensive multimedia work) . Thus, it is likely that your computer does not have enough memory(commonly called "RAM" or random access memory) to perform the task of opening a file.
Files with *.img extension. These are images of mounted disks according to the Macintosh standard (Macintosh-Disk-Image). It can be launched using such software products as, for example: Deamon Tools, Alkohol120% . It works like a DVD drive with a disk (only in this case it is virtual), or a separate partition on the hard drive. It can also be written to disk.
They are used to install software and games without the original disk itself, or in the absence of a DVD drive, which is not uncommon on modern laptops, or to copy (create) boot disks.
Files with the *.img extension are more often found in operating systems of the Mac OS family, but in operating systems of the Windows generation they also work with them using the following programs: Sly Soft Clone CD, H + H Software Virtual CD, Lightning-UK! Img-Burn SmartProjects, Iso-Buster, EZB Systems, Ultra ISO, Magic ISO and the above mentioned Deamon Tools, Alkohol120%. The principle of operation is the same.
A very effective software tool with which you can create a virtual disk for working with an IMG file in just a few clicks. A simple interface and only mega-productive functions make this software the most popular not only among the novice group of users, but also among advanced users.
Download the free version of DaemonTools to your PC (click here!).
In the main program window (in the lower left corner), click on the icon in the drive view.
Select the IMG image.
Click on the "Open" button.
Next, double-click to launch the image file.
If the service invitation window does not appear, then go to the “This PC” section (go to the “Start” menu or look for a shortcut on the desktop).
As a rule, the virtual disk is the last one in the list of used hard disk partitions and external storage devices (flash drive) connected to the PC.
Activate the drive by double-clicking the left mouse button.
After you have managed to download the IMG file to the virtual disk, you can start the playback process or familiarize yourself with all its contents in detail.
Small but very effective ExtraсtNow unpacker utility
If you want to continue viewing the contents of the IMG file container, then special attention should be paid to this program. Don't be wary - the small size of the program is deceptive - this is really a very solid software in its functionality.
The extractor is capable of working and easily recognizes almost all known archive extensions. All you need to do to open an IMG file is drag the file container into the program window and press the “Extract” key. By the way, here is the download link: http://download.cnet.com/ExtractNow/3000-2250_4-10038365.html.
To open an IMG file, you can use the following programs:
Nero Burning ROM is a well-known software product, most often used to work with images of another format - .nrg. There is no free version, you must purchase a license;
Daemon Tools Lite – free lightweight version can be used to open IMG;
UltraISO – there should be no problems finding and downloading the utility. The program is easy to install on your computer, but without purchasing a license it can only work with files less than 200MB. Using this utility, you can not only open an img file on a virtual drive, but also burn a CD/DVD (subject to the stated limitations).
Among the many different file formats, IMG is perhaps the most versatile. And this is not surprising, because there are as many as 7 types of it! Therefore, when encountering a file with such an extension, the user will not immediately be able to understand what exactly it is: a disk image, an image, a file from some popular game, or geographic information data. Accordingly, there is separate software to open each of these types of IMG files. Let's try to understand this diversity in more detail.
In most cases, when a user encounters an IMG file, they are dealing with a disk image. Such images are made for backup or for more convenient replication. Accordingly, you can open such a file using programs for burning CDs, or by mounting them in a virtual drive. There are many different programs for this. Let's look at some of the ways to open this format.
Method 1: CloneCD
Using this software product, you can not only open IMG files, but also create them by removing an image from a CD, or burn a previously created image to an optical drive.
The program interface is easy to understand even for those who are just beginning to comprehend the basics of computer literacy. 
It doesn't create virtual drives, so you won't be able to view the contents of an IMG file with it. To do this, you need to use another program or burn the image to disk. Along with the IMG image, CloneCD creates two more service files with the CCD and SUB extensions. In order for the disk image to open correctly, it must be in the same directory as them. There is a separate type of program called CloneDVD for creating DVD images.
The CloneCD utility is paid, but the user is offered a 21-day trial version for review.
Method 2: Daemon Tools Lite
Floppy disk image
In the distant 90s, when not every computer was equipped with a drive for reading CDs, and no one had ever heard of flash drives, the main type of removable storage media was a 3.5-inch floppy disk with a capacity of 1.44 MB. As with CDs, images could be created for such floppy disks for backup or replication of information. This image file also has an IMG extension. We can guess that this is a floppy disk image, first of all, by the size of such a file.
Currently, floppy disks have become deeply archaic. But sometimes these media are used on outdated computers. Floppy disks can also be used to store digital signature key files or for other highly specialized needs. Therefore, it will not be superfluous to know how to open such images.
Method 1: Floppy Image
This is a simple utility with which you can create and read floppy disk images. Its interface is also not particularly pretentious. 
Simply indicate the path to the IMG file in the appropriate line and click the button "Start" how its contents will be copied to a blank floppy disk. It goes without saying that for the program to work correctly, you must have a floppy drive on your computer.
This product is currently no longer supported and the developer's website is closed. Therefore, it is not possible to download Floppy Image from an official source.
Method 2: RawWrite
Another utility, identical in principle to Floppy Image.
To open a floppy disk image you need to:
- On the tab "Write" specify the path to the file.
- Click the button "Write".
The data will be transferred to the floppy disk.
Raster image
A rare type of IMG file, once developed by Novell. It is a bitmap image. In modern operating systems, this type of file is no longer used, but if the user comes across this rarity somewhere, it can be opened using graphic editors.
Method 1: CorelDraw
Since this type of IMG file is the brainchild of Novell, it is quite natural that you can open it using a graphics editor from the same manufacturer - Corel Draw. But this is not done directly, but through the import function. To do this you need to do the following:
As a result of these actions, the contents of the file will be loaded into Corel. 
To save the changes in the same format, you need to export the image.
Method 2: Adobe Photoshop
The most popular graphics editor in the world can also open IMG files. This can be done from the menu "File" or by double-clicking on the Photoshop workspace. 
The file is ready for editing or converting. 
You can save the image back to the same format using the function "Save as".
The IMG format is also used to store graphic elements of various popular games, in particular GTA, as well as for GPS devices, where it displays map elements, and in some other cases. But all these are very narrow areas of application that are of more interest to developers of these products.
IMG is a format for mounting images of optical and hard drives. Today there are more than 10 popular programs available that work with IMG, but mounting utilities are limited. A virtual disk emulator or an archiver can open files for use and viewing. In this article, read how to open an IMG file on your computer.
general description
IMG was used to create virtual disk images. It is now considered obsolete and is not used. IMG extension files, like other similar formats (iso, mdx, mdf), were used to make copies from optical media or to backup information from hard drives. When files of this extension were placed on the computer, the PC perceived them as a disk or external media inserted into the drive. The peculiarity of the format is that it is similar in structure to an archive - the information is placed in one file.
When copying installation disks, this format became a complete analogy of the source, preserving the content and file system. So, when copying content from an installation disk to another disk without an emulator program, the copy did not become an installation disk. However, if a virtual disk emulator was used that created an IMG extension file that was burned to a CD or DVD, then the copy became a complete analogue of the source.
IMG was developed for Mac OS and was used by this system until Mac OS 9. In later builds, the format was replaced by dmg.
A virtual disk is not the only type of IMG format. There are also:
Raster images - graphic editors such as, etc. work with such files;
Game files – IMG files are specific to the GTA game. Ordinary users are unlikely to encounter this type of IMG extension. The program is capable of opening this.
How and with what to open an IMG extension file
To work with IMG, open or view such a file, you need archivers or disk emulators. The difference is that the archiver can only download the contents and place them in a separate folder, while the emulator will create a full-fledged image of the optical disk, which will be one file on the computer. They will not differ in the amount of space they occupy, but the archiver will create many files, and the emulator will create one.
Open on computer
How to open an IMG file on a computer:
– a popular emulator program that works with 40 formats;
– emulator program for mounting, editing and viewing virtual disks;
– archiver, not capable of mounting images, but suitable for viewing IMGs;
The interface of these programs is similar to each other, with the exception of the archiver. In emulators, in order to open this format, you need to either drag it to the program’s work panel, or find it through the “File” - “Open” tab, indicating it in the address bar. The key responsible for creating an image in different programs has a different name and can be indicated by a “+” sign, or called “mount”, “create image” or similar variations of this phrase.
On windows 7
The seventh version of Windows does not provide standard programs for working with IMG. This format can only be opened using the utilities listed above.
On windows 10
Probably due to the fact that IMG is a Mac OS format, and an outdated one at that, Windows developers did not create standard services for working with even the latest version of their OS, unlike the iso format. As with early OS builds, the file will not work without the help of emulators or archivers. The situation is similar with Mac OS; without the help of third-party services it will not work.
If you suddenly find an unknown img file on your favorite computer (for example, you copied it from a friend’s flash drive or downloaded it from the Internet), but you don’t know how to open it, don’t be scared or upset. Of course, you can try to find out from a friend how to open img, however, firstly, it is not always possible to find a knowledgeable friend, and secondly, it is better to try to figure it out yourself. And this article will help you in this difficult matter, because it is devoted specifically to the question of how to open an img file.
If there is a file in the folder in front of you in the img format, which you have no idea how to open, first of all you should figure out what kind of format it is.
Img, contrary to the opinion of many users, is not an image or picture at all. Of course, many people associate img with image, but in this case the word is translated as “image”. That is, the IMG file is a disk image, a kind of ISO analogue, only with slightly different algorithms for reading and, accordingly, writing the image. It should be noted that often simply changing the img file extension to iso makes it possible to open files in programs where img formats are not supported.
This format has been widely used for creating disk images in the Macintosh environment, but is also quite common in Windows applications.
In Mac OS X, the .img format was replaced by the .dmg extension. And if in Mac OS this format can be both an image and a hard disk image, then in Windows it is used only for emulating CD/DVD media. As a rule, in Windows OS files of this format are created by the CloneCD program. And the full image will be supplemented with .ccd and .sub files with similar names.
But still, we will try to directly answer the question of how to open img. The most popular programs for working with this format are NERO, Daemon Tools and UltraISO.
First, let's figure out exactly how to work with files of this format. As with any other disk images, you can emulate the operation of img in a virtual drive on your computer. In addition, the image can be written to a real laser disk and then used in a regular drive.
UltraISO disk image program
To download the distribution of this program to your computer, just type its name in any search engine and follow the link provided. This program installs and works quite simply. Install the UltraISO program on your computer, following all the prompts, then restart the computer. Everything is ready to go. To simply solve the problem of opening img, you don’t need to open the program at all. You just need to find a disk image of this format in the folder, right-click on it and thereby call up the “UltraIso” line in the menu, where in the drop-down menu select the appropriate type of action. You can immediately mount the disk image into a virtual DVD drive or burn the image to a real disk.
To burn an image to a disk, you need to insert a blank disk into the drive and click on “burn”. Just be sure to check whether your DVD-ROM or CD-ROM is recordable. If the device does not have such a function, then, accordingly, you will not be able to burn the image to disk. But don’t despair, because you can still run the disc in a virtual drive. The UltraIso program will help you not only open an img file, but also burn it to a real disk - easily and universally!
We will not consider working with the NERO and Daemon Tools programs, since these programs will require you to purchase a license. And the free versions are not convenient.
Now you know how to open img on your computer. I hope that files of this format will not cause you any inconvenience. If you also have iso images on your computer, they open in the same way.
