How to Open and Extract IMG Files on Windows

An IMG file is a disk image that stores a sector-by-sector copy of a disc or another storage device. The .img extension is fairly generic, so two IMG files can contain very different file systems or data. Some are optical-disc images similar to ISO files, while others may come from hard drives, USB drives, memory cards, software installers, or older media.

That difference matters when you try to open one. If Windows recognizes the image structure, you can mount it and browse the contents as a virtual drive. If it does not, an archive or image utility may still be able to read and extract the files. You do not normally need to burn the IMG file to a CD or DVD first.

Note: An IMG file can also be a DVD-Video disc image containing a movie DVD structure. That is a more specific use case and is not the main focus of this guide. If your goal is to open a DVD-Video IMG and convert the movie to a regular video file, see how to convert a DVD IMG to video.

Many IMG disc images can be opened in Windows by mounting them as a virtual drive. If your system provides a built-in Mount option, locate the .img file, right-click it, and choose Mount. The image will then appear in This PC or Computer, where you can browse its contents just like a physical disc.

If double-clicking the file opens 7-Zip, WinRAR, or another app instead, right-click the IMG file and choose Open with > Windows Explorer when that option is available. When you are finished, right-click the virtual drive in This PC or Computer and choose Eject.

Note: Because IMG is a generic image extension, File Explorer may not show Mount for every .img file. That does not necessarily mean the file is damaged. Its internal layout or file system may simply be one that Windows cannot mount natively. In that case, try a third-party mounter or extract the image instead.

If File Explorer cannot mount the image but you want to use it as a virtual disc instead of extracting it, a third-party image mounter can help. DAEMON Tools Lite is one option and its current free edition can mount popular image types, though the free installer is ad-supported.

Step 1: Download and install DAEMON Tools Lite from https://www.daemon-tools.cc/products/dtLite.

Step 2: Launch the program and click Quick Mount, then select your IMG file.

Step 3: Open This PC. If the image is supported, it will appear as a new virtual drive.

Step 4: Double-click the virtual drive to browse the files. Unmount or eject it when you are done.

Mounting is convenient when you want to run or browse an image as a virtual disc. If you only need the files inside, extracting the IMG to a normal folder is often simpler. This also helps when Windows cannot mount the image.

👉 Method 1 - Extract an IMG File with 7-Zip

7-Zip is free and open-source. It can unpack many file systems and disk-image structures, so it can open many IMG files when their contents are recognized.

Step 1: Install 7-Zip, then right-click the IMG file.

Step 2: Open the 7-Zip menu from the context menu, then choose Open archive or an extraction option.

Step 3: Choose Open archive if you want to inspect the contents first, or choose Extract files... or Extract to "folder" to unpack them.

Step 4: Select an output folder and start extraction. If 7-Zip reports that it cannot open the file as an archive, try AnyBurn or a dedicated disk-image tool instead.

👉 Method 2 - Browse and Extract an IMG File with AnyBurn

AnyBurn is another option for disc and disk image files. Its free edition includes the ability to browse and extract image files.

Step 1: Open AnyBurn and choose Browse / Extract image file.

Step 2: Browse to your IMG file and open it. AnyBurn will try to detect the image format and list the files and folders it can read.

Step 3: Select the items you want to extract. If you select nothing, you can extract all available contents.

Step 4: Choose the destination folder and click Next to start extraction.

1. Why is there no Mount option for my IMG file?

The .img extension can be used for different kinds of disk images. Windows may not recognize the particular layout or file system in your image, or another program may have taken over the file association. Try Open with > Windows Explorer first. If Mount still is not available, use a compatible third-party mounter or extract the files with 7-Zip or AnyBurn.

2. Does extracting an IMG file change the original image?

No. Extraction copies readable files from the image to a folder and leaves the original IMG file unchanged.

3. Can I rename .img to .iso to open it?

Renaming the extension does not actually convert the image. It may appear to work only when the IMG already uses an ISO-compatible structure. For other images, use a proper image conversion tool instead of relying on a filename change.
