OSFMount 1.5.1011 (Freeware)

OSFMount supports 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 lost.

OSFMount supports mounting CD iso images, which can be useful when a particular CD is used often and the speed of access is important.
