Windows 8 and Windows 10 comes with an inbuilt feature to mount ISO files on a virtual drive. However, if you are still using Windows 7 or previous Windows versions, you have to use a third-party tool to mount an image file, for instance, gBurner Virtual Drive, WinCDEmu, or Virtual CloneDrive, etc.
PassMark OSFMount is a powerful tool available for Windows PC that lets you mount an image file on a virtual disk. It mounts local disk image files in Windows as a physical disk or a logical drive letter. Once you mount the image file to a virtual disk, you analyze the disk data, play audio/files, or whatever the data stored in the image file. By default, the image files are mounted as read-only so that the original image files are unchanged.
The beauty of the OSFMount is that it supports mounting disk image files as read/writes in “write cache” mode. This software stores all writes to a “write cache” file, which preserves the original disk image file’s integrity.
OSFMount features the facility to create RAM disks, in other words, a disk mounted into RAM. This feature provides a large speed benefit over using a hard disk. It is useful when working with applications requiring high-speed disk access, such as database applications, games, etc. Another benefit of mounting image files on RAM is, disk contents are not stored on a physical hard disk (but rather in RAM), and on system shutdown, the RAM’s data get erased automatically.
PassMark OSFMount software lets you mount ISO, VMDK, BIN, ISO, IMG, VHD, NRG, AFF, AFD, and other format files. Once you install it on your PC, you can create multiple virtual drives and view the list of all those drives on its interface. You can dismount individual image files or all image files at once. This freeware tool can also create virtual RAM disks, which helps mount an image file to a virtual RAM disk instead of a virtual disk.
PassMark OSFMount is easy to use software and comes with a nice user interface. Just open its interface and click Mount new button. You can also use the File menu to mount an image file. Now a separate window will open. Select the Disk image file option. Here, you will also find an option to checkmark “Mount as RAM drive” to mount the image file to RAM.
After that, click on the browse button (…) to select an ISO image from your PC and press the Next button. In the next step, it automatically selects the mount entire image as a virtual disk option. Go to the next step and select options as per your need.
It is compatible with all versions of Windows, including Windows XP, Vista, 7, 8, and 10.
The PassMark OSFMount is free to use software, and you can download it from its official webpage. There are two separate files available for 32-bit and 64-bit operating systems; make sure to download the correct one for your PC.
