ImDisk is a virtual disk driver for Windows NT/2000/XP/Vista/7/8/8.1/10 and Windows Server 2003/2003 R2/2008/2008 R2/2012/2012 R2, 32 and 64 bit editions. It can create virtual hard disk, floppy or CD/DVD drives using image files or system memory. The install package installs a console-mode control program called imdisk.exe and a Control Panel applet . After install is finished, type imdisk without parameters for syntax help or double click the ImDisk icon in the Control Panel. It also adds a menu item in Windows Explorer so that you can right-click on a file to mount it as a virtual disk drive.
Recent versions of Windows support mounting virtual ISO discs.
