OSFMount lets you mount ISO, IMG, BIN, VHD, VMDK and other disk image files as virtual drives in Windows. Access partitions safely, create high-speed RAM drives, and manage local image files without unnecessary bloat.
What Is OSFMount?
OSFMount is a Windows utility that lets you open and access disk image files without burning them to a physical CD, DVD, or USB drive. It mounts a complete disk or an individual partition as a virtual drive, so the stored files appear directly inside Windows File Explorer.
Turn a disk image into an accessible Windows drive.
Select an image file, assign a drive letter, and browse its contents just like a normal local disk.

Is OSFMount suitable for forensic disk images?
OSFMount can help professionals mount and access supported forensic disk images, especially in read-only mode. It does not replace a complete forensic analysis platform.
Can I mount a specific partition?
Yes. When a complete disk image contains multiple partitions, OSFMount can allow you to select a supported partition and mount it separately.
What happens to RAM drive data after shutdown?
RAM drive data is normally temporary and may be lost when Windows shuts down or restarts. Save important files to permanent storage before turning off the computer.
Does OSFMount require administrator access?
Administrator permission may be required to install the software, load its driver, create virtual drives, and manage certain mounting operations.
Can OSFMount open RAW disk images?
