To open an IMG file, options depend on the file type and usage: For an image file:- Use an image viewer or editor, such as Windows Photos, Paint, or GIMP. Open the file, right-click, select "Open with," and choose your software. For a disk image:- Burn it to CD/DVD via disk burning software, such as ImgBurn. Or, mount it as a virtual disk via software like WinCDEmu or Virtual CloneDrive. For an archive:- Use archive software like 7-Zip or WinRAR to extract its contents. Right-click the file, select "Extract," or "Extract here" to unzip the contents to a folder.
