Free and straightforward software to mount different types of disk drive images with the option to save and export disks as ISO, IMG, AFF or other image formats.
OSFMount is a freeware virtual disk app and CD burner, developed by PassMark Software for Windows. It's pretty straightforward.
The download has been tested by an editor here on a PC and a list of features has been compiled; see below. We've also created some screenshots of OSFMount to illustrate the user interface and show the overall usage and features of this virtual disk program.
Mount as many ISO disc images as you want as virtual drives
OSFMount allows you to mount local disk image files (bit-for-bit copies of a disk partition) in Windows with a drive letter. You can then analyze the disk image file with PassMark OSForensics by using the mounted volume's drive letter. By default, the image files are mounted as read only so that the original image files are not altered.
OSFMount also supports the creation of RAM disks, basically a disk mounted into RAM. This generally has a large speed benefit over using a hard disk. As such this is useful with applications requiring high speed disk access, such a database applications, games (such as game cache files) and browsers (cache files). A second benefit is security, as the disk contents are not stored on a physical hard disk (but rather in RAM) and on system shutdown the disk contents are not persistent.
OSFMount supports mounting images of CDs in .ISO format , which can be useful when a particular CD is used often and the speed of access is important.
