ImDisk vs OSFMount

ImDisk is a free Windows virtual disk driver for creating disk volumes from image files or system memory. It can present virtual hard disk partitions, floppy drives, and CD/DVD drives, with support for raw images, VHD, VDI, VMDK, NRG, SDI, and BIN formats. The installer provides the imdisk.exe console tool, a Control Panel applet, and an Explorer command for mounting files. I/O requests can be passed to third-party image handlers or services on other computers over a network. API functions are available to C/C++, COM, and .NET applications, with wrapper libraries on NuGet. The current installer supports 32-bit and 64-bit Windows and lists x86, ia64, x64, arm32, and arm64 architectures. ImDisk is free to download and use; a voluntary usage fee is welcome. The maker says it receives maintenance fixes, but no new features are planned and its legacy design is not recommended for recent Windows versions.
