WinImage

Win Image gives you an Explorer-like window on a disk image. You can create images, browse directories, and drag and drop files. Win Image supports images for FAT floppies and hard disks, and CD-ROMs (ISOs). It will also extract an image from a disk, or write an image to a disk. One drawback is that it's shareware, unlike File Disk and MTools, so if you want to use all of its features after the evaluation period expires, you will need to pay.
