ImDisk Virtual Disk Driver for Windows NT/2000/XP/2003/Vista/7/8/8.1/10

PLEASE NOTE: This project is not recommended on recent versions of Windows and many applications written for Windows Vista and later require features that are not supported. It is based on an old design for compatibility with as old versions as Windows NT 3.51. No new features will be added to this project but it will remain available here because it could still be useful in certain scenarios.

I will continue development of Arsenal Image Mounter instead. That has a different design and emulates complete disks and is compatible with most cases where physical disk are normally used. https://github.com/ArsenalRecon/Arsenal-Image-Mounter

Back to this project, ImDisk Virtual Disk driver. This driver emulates harddisk partitions, floppy drives and CD/DVD-ROM drives from disk image files, in virtual memory or by redirecting I/O requests somewhere else, possibly to another machine, through a co-operating user-mode service, ImDskSvc.

To install this driver, service and command line tool, right-click on the imdisk.inf file and select 'Install'. To uninstall, use the Add/Remove Programs applet in the Control Panel.

You can get syntax help to the command line tool by typing just imdisk without parameters.

I have tested this product under 32-bit versions of Windows NT 3.51, NT 4.0, 2000, XP, Server 2003, Vista, 7, 8, 8.1 and 10 and x86-64 versions of XP, Server 2003, Vista, 7, 8, 8.1 and 10. Primary target are older versions and there are several known compatibility issues on modern version of Windows. Please see website for more details: https://ltr-data.se/opencode.html#ImDisk

The install/uninstall routines do not work under NT 3.51. If you want to use this product under NT 3.51 you have to manually add registry entries needed by driver and service or use resource kit tools to add necessary settings.

To install/uninstall on ARM or ARM64 architectures a manual setup is needed. More about that and other frequently asked questions in the wiki: https://github.com/LTRData/ImDisk/wiki
