Mount Disk Images With OSFMount

OSFMount is a free program for the Windows operating system that ships with an interesting set of features to mount disk images.

Disk images come in various formats and sizes, from tiny floppy drive images to huge bit to bit copies of partitions or entire hard drives. These disk images can be mounted, which basically means that they become accessible under a drive letter on the operating system.

Mounting images can be interesting for several reasons: from playing games without the need for the original DVD in the drive, over watching movies without the video DVD, to recovering data from an image of a corrupt hard drive.

Disk images can be created by specialized applications, and also downloaded from the Internet. Microsoft is for instance distributing disk images of their applications regularly, and many Linux distributions are provided as disk images as well. Some programs can access disk image formats directly, CD and DVD burning software for instance, while others can only access the data if the image has been mounted first.

OSFMount is a lightweight software for Windows that supports a variety of disk images. Among the supported formats are popular disk image formats such as ISO, Bin, IMG and NRG plus some exotic formats like DD, VMDK and AFD.

The program lacks support for some lesser used disk image formats, like mdf or ccd, but comes with a handful of extra options that are not commonly found in disk image programs.

Disk images are mounted with a click on Mount New, the keyboard shortcut Alt-n or the selection of File > Mount New Virtual Disk.

The mount drive window offers to mount disk images the default way or using RAM. A supported disk image format needs to be selected with the help of the file browser after you have made that selection.

RAM may be interesting under certain circumstances, for instance if you want to perform operations using the data (lots of copying or processing for instance) as it is a lot faster then.

Advanced options include selecting an image file offset, the size of the drive, drive letter and drive type. All disk images are mounted as read only drives by default which can be changed in the program options as well.

It is furthermore possible to create an empty ram disk that is then accessible via the mapped drive letter.

All mounted disk images become available immediately, empty disks needs to be formatted before they can be used.

The main interface lists all mounted virtual disks, and disks can be unmounted at anytime. A right-click displays a context menu with additional options, among them the option to change the size of a disk image, save the current data to a supported disk image format or make the disk read-only or writable.

The ability to write data could be interesting for some users. You could use the option to create a ramdisk, install applications to it, save the state of the ramdisk to a disk image format once you are finished working for the option to mount the image again at a later time.

The program seems to support as many mounted disk images as free drive letters are available.

Interested users can download OSFMount from the developer website. It is provided as a 32-bit and 64-bit application there that supports all major client and server versions of the Windows operating system.

    Like the simplicity of setting the RAM drive versus some other options out there.

    Is it faster then daemon tools ?

    • Martin Brinkmann March 25, 2011 at 10:56 am #

      Depends on how you define faster.

      • Pijus March 25, 2011 at 11:41 am #

        You know.. loads image faster, program start time. Tried osf mount, compared to daemon I cant tell the difference on image loading speed ant start time. Imo daemon got more user friendly meniu :)

        I do not think there is a need to switch if you are happy with Daemon Tools and cannot see a difference on first glance ;)

    Other than daemon tools comes with that "other" software; if you have avoided installing any of that...

    I have failed to understand something really basic about OSFmount.

    1) Mount image
    2) Open image to use
    3) "Format it before you use it"
    4) Format wipes image
    5) Open virtual disk (now you're allowed to)
    6) Nothing there.

    I'm being an idiot aren't I. There is something obvious here that will make it work. Please take pleasure in telling me what I've failed to do.

    All the best, G.
