Source code

Source code for all of ImDisk Virtual Disk Driver, including the devio server-side tool, API libraries etc is available as a 7-zip compressed file here (308.0 KB). Different parts of the source tree are built in different environments:

• The Windows drivers, command line tool and Control Panel applet parts of the source code are built with WDK 7.1.0. There is a Makefile in the source tree root that builds imdisk.sys, awealloc.sys, imdisk.cpl, imdisk.exe and imdsksvc.exe when ran with nmake in WDK 7.1.0 command prompts.
• The devio server side tool used with ImDisk clients in proxy mode, can be built with most *nix C++ compilers like gcc and similar. It can also be built in most Visual Studio/C++ command prompts. In all cases the devio binary you get supports listening for a tcp/ip connection and serving either a raw image file or a Microsoft vhd image file and parsing MBR partition tables to find offsets and sizes. When built with Visual Studio/C++ compilers, you will get a devio.exe that also supports listening for shared memory connections, the --dll switch to load custom dlls for accessing custom image file formats and features for auto-finding sizes of a physical devices.
• The .NET library located in ImDiskNet subdirectory can be built using Visual Studio 2010 or higher, any edition with Visual Basic support.
• There is an experimental Visual Studio solution with some project files for the driver, Control Panel applet, imdisk.exe and devio.exe. This is not yet ready for production use, but could be used to open files for easier editing in Visual Studio development environment, even if you likely need to switch to WDK 7.1.0 command line to build.

Compatibility

ImDisk Virtual Disk Driver is designed to be a small, simple and yet powerful virtual disk driver. It runs on very old versions of Windows NT as well as modern Windows versions. However, because of this compatibility design and because it emulates disk volumes rather than complete disks, it is not always compatible with all applications and drivers. For instance, you cannot manage things like mount points, drive letters and similar for ImDisk drives using mountvol command line tool or in Disk Management in Windows. As another example, you cannot create or access shadow copies on ImDisk drives. So, applications that use similar Windows features as Disk Management dialog to enumerate disks and disk volumes to find disk properties like sector sizes and similar, might possibly not work as expected with ImDisk drives.

Arsenal Image Mounter - If you need full disk emulation support

If you need full disk emulation, including integration with Disk Management, Volume Shadow Copy Services, mountvol and diskpart command line tools as well as better compatibility with applications, we provide another open source virtual disk project, called Arsenal Image Mounter. It is published together with Arsenal Recon and is available for download here. It is available for non-commercial use under AGPL license. Commercial license options available, please contact Arsenal Recon for more information. Source code, command line tools, driver setup packages and similar for Arsenal Image Mounter are available on GitHub. The directory structure is desribed in this document.

Small command line utilities

• bzip2.zip - 33.2 KB (32 bit) / bzip264.zip - 39.6 KB (64 bit) / bzip2.zip - 34.7 KB (ARM)
  compiled 2018-05-13
  The very space efficient bzip2 compression utility with huffman/deflate algorithms. This port is from the XMILL project. The binary here is optimized for Pentium 4 processors but will run on other x86 processors as well and is linked with the minwcrt library so the exe file is smaller and does not require msvcrt.dll like many other Win32 ports of the GNU version does.
  
• calldll.zip - 14.2 KB (32 bit) / calldll64.zip - 15.1 KB (64 bit) / calldll.zip - 9.4 KB (ARM)
  compiled 2018-11-11
  - Calls a function in a dll file. The function must use the stdcall calling convention and accept only one single parameter, a pointer to a character string as or a NULL pointer. If you e.g. want to connect to a network printer from a batch file you can write: "calldll winspool.drv AddPrinterConnectionA \\server\printerq". The ZIP file also contains calldllw.exe which is exactly the same except that it passes a unicode string instead of ansi. That version can only be used in Windows NT/2000/XP/2003.
  
• chsize32.zip - 8.8 KB (32 bit) / chsize3264.zip - 8.3 KB (64 bit) / chsize32.zip - 9.5 KB (ARM)
  compiled 2018-11-11
  Changes file size of existing file or creates a new file with specified size.
• copyacls.zip - 8.7 KB (32 bit) / copyacls64.zip - 9.4 KB (64 bit) / copyacls.zip - 11.6 KB (ARM)

  compiled 2018-05-13
  My Win32 port of the BSD cut utility. This version is a much smaller exe file than e.g. K M Syring's Win32 port of the GNU cut utility. Additionally, because this version does not require msvcrt.dll it will run without additional files even on very old versions of Windows NT.
• devioctl.zip - 14.9 KB (32 bit) / devioctl64.zip - 14.9 KB (64 bit) / devioctl.zip - 17.7 KB (ARM)
  compiled 2018-11-11
  Command line interface to the basic disk device functions of DeviceIoControl() API. Used to unmount a filesystem, load or eject e.g. a CD. Requires Windows NT/2000/XP/2003.
• dosdev.zip - 8.8 KB (32 bit) / dosdev64.zip - 9.2 KB (64 bit) / dosdev.zip - 10.4 KB (ARM)
  compiled 2018-11-11
  Command line interface to the DefineDosDevice() and QueryDosDevice() API functions. Defines, redefines and prints information about the emulated DOS devices in Windows NT. Very useful if you want to use any object in Windows NT object namespace from ordinary Win32 applications. (In Windows 95/98/ME this utility is equivalent to the SUBST command.)
• enumproto.zip - 7.3 KB (32 bit)
  compiled 2016-03-11
  Utility to display and optionally remove installed Winsock LSP modules Layered Service Providers. Today many spyware/adware/malware install LSP modules to capture network traffic and send statistics to some company. After removing such spyware Winsock APIs may fail for all applications because there are registry references to LSP modules that no longer exists. In Windows XP SP2 you can reset LSP chain using the command netsh winsock reset but with earlier versions it was almost impossible without reinstalling the TCP/IP protocol, as described in KB892350 or KB817571. The enumproto simplifies the procedure of removing LSP modules from the chain and can run on Windows 95 (with Winsock 2.x), 98, ME, NT 4.0, 2000, XP and Server 2003.
  
• enumps.zip - 8.9 KB (32 bit) / enumps64.zip - 10.1 KB (64 bit) / enumps.zip - 11.2 KB (ARM)
  compiled 2018-11-11
  Utility to display names of running processes, which dll modules are loaded into different processes and numbers and owner processes of running threads. Requires Windows 95/98/ME/2000/XP/2003. It does not work on Windows NT 4.0 or earlier, use psmod instead to enumerate loaded dll files or the pslist tool by SysInternals to enumerate running processes.

To use SSL/TLS encryption and/or encrypted authentication, please try the more modern versions in MailTools.zip described further down this page.
• popman.zip - 11.1 KB (32 bit)
  compiled 2018-11-11
  Useful to list messages in a POP mailbox and delete a message you don't want to receive directly on the server. Useful e.g. if you have a low bandwidth connection and can't receive the e-mail you want just because there is a really big e-mail first at the server... This application supports clear text connections and clear text authentication only. To use SSL/TLS encryption and/or encrypted authentication, please try the more modern versions in MailTools.zip described further down this page.
• psmod.zip - 8.6 KB (32 bit) / psmod64.zip - 9.3 KB (64 bit) / psmod.zip - 10.5 KB (ARM)
  compiled 2018-11-11
  Utility to display which dll modules are loaded into different processes. Requires Windows NT 4.0 or 2000/XP/2003. On Windows NT 4.0 the psapi package is required, if you don't have it, i.e. the program complains about psapi.dll, you can get it here. For Windows 95/98/ME platforms, use the enumps tool instead.
  
• rawcopy.zip - 14.8 KB (32 bit) / rawcopy64.zip - 14.4 KB (64 bit) / rawcopy.zip - 17.2 KB (ARM)
  compiled 2018-11-11
  Reads and writes files and devices. (Cannot read/write disk devices in Windows 95/98/ME or Win32s.) For example useful to write a floppy image file on a hard disk to a physical floppy in Windows NT. (This can also be done by using various Win32 ports of the *nix dd program. But unlike my rawcopy, they usually do not unmount/lock physical devices or partitions during the read/write which makes them quite dangerous to use if anything else is using the device meanwhile...) From version 1.2.1 it can also create sparse output files with a new -s command line switch. Version 1.3.0 supports differential copying.
  
• reptxt32.zip - 10.3 KB (32 bit) / reptxt3264.zip - 10.1 KB (64 bit) / reptxt32.zip - 11.3 KB (ARM)

• setprio.zip - 9.6 KB (32 bit) / setprio.zip - 12.1 KB (ARM)
  compiled 2018-11-11
  Displays information about and optionally changes the priority class for a given process id. (Same function as the priority change option in Task Manager, but this is a command line tool that works in Windows 95/98/ME too.) This program does nothing when run in Win32s on Windows 3.x (because there is no process and thread scheduler in Windows 3.x).
• shortren.zip - 8.1 KB (32 bit) / shortren64.zip - 8.5 KB (64 bit) / shortren.zip - 10.2 KB (ARM)
  compiled 2018-11-11
  Changes the short filename (MS-DOS compatible 8.3) alias of a file or directory with a long name or a name with characters not allowed in MS-DOS filenames. Requires Windows XP, Server 2003 or later.
• sizdir32.zip - 13.7 KB (32 bit) / sizdir32.zip - 15.4 KB (ARM)
  compiled 2018-11-11
  Lists all files in a given size interval in current directory and all subdirectories and then displays how much disk space the files use and how much they would use if the allocation block size were changed.
• sizeof.zip - 10.6 KB (32 bit) / sizeof64.zip - 11.0 KB (64 bit) / sizeof.zip - 13.3 KB (ARM)
  compiled 2018-11-11
  Shows total size on disk for files or directories. For directories it shows total for all files in that directory, it uses backup privileges (if avaiable) to count all files, regardless of whether the current user can access them or not. It also shows compressed or sparse size rather than virtual size for such files. This tool counts one file only once, even if there are several hard links to the same physical file. There is also an option to skip reparse points (to let subdirectory search stay within one filesystem).
• strarc.zip - 34.7 KB (32 bit) / strarc64.zip - 41.5 KB (64 bit) / strarc.zip - 32.2 KB (ARM)
  compiled 2018-11-11
  A console backup/archive tool for all versions of Windows NT from NT 3.51 up to Windows 10. It uses the same backup methods as the ntbackup or robocopy programs and thus backs up all information and meta data on an NTFS volume. The main difference is that strarc is free and open source and produces stream archives you can store on tapes, disks or anywhere else or it can create the archive stream to stdout so that it can be compressed easily using stream compression tools like gzip or bzip2. The command line switches and parameters are quite similar to the *nix tar utility and it can easily be used to clone an entire NTFS volume including everything, files, directories, their time stamps, attributes and security information, compression attribute, alternate data streams, junctions, hard links etc. It is now even possible to backup the registry database files of a running Windows system. An information file called strarc.txt describing usage and including how-to:s and other documentation is included in this zip file. The documentation is also available here.
• swapadd.zip - 8.3 KB (32 bit) / swapadd64.zip - 8.6 KB (64 bit) / swapadd.zip - 10.7 KB (ARM)
  compiled 2018-11-11

• tickcount.zip - 7.5 KB (32 bit) / tickcount.zip - 10.7 KB (ARM)
  compiled 2018-11-11
  Displays information about how long time the system has been up. (Weeks, days, hours, minutes, seconds and milliseconds.)
• txtcnv32.zip - 8.8 KB (32 bit) / txtcnv3264.zip - 9.4 KB (64 bit) / txtcnv32.zip - 10.9 KB (ARM)
  compiled 2018-11-11
  Converts text files or text streams from ANSI codepage to OEM codepage or vice versa. It is also possible to specify codepages to convert from and to, or to convert from or to 16-bit Unicode (UTF16) from or to a specific codepage.
• w32ver.zip - 12.5 KB (32 bit) / w32ver.zip - 9.3 KB (ARM)
  compiled 2018-05-13
  Displays the current version number, build number and service pack level for the current Win32 environment. w32verc.exe displays the information in the console window and w32ver.exe displays it in a dialog box making it compatible with Win32s on Windows 3.x.
• whois.zip - 20.1 KB (32 bit) / whois.zip - 23.0 KB (ARM)
  compiled 2018-11-11
  My Win32 port of the GNU whois client. Automatically directs the query to the right whois server by using tables and following redirections. Now updated to support the new .eu domains.
  
• xcopynt.zip - 9.7 KB (32 bit)
  compiled 2018-11-11
  Copies a complete directory tree to another location. This tools copies files, directories (even empty ones), all attributes, extended attributes, time stamps, security information including access permissions (except in some cases owner and auditing information). Requires Windows NT 4.0, Windows 2000, XP or Server 2003. The Windows NT 4.0 version of xcopy.exe did not have all this functionality. Note! The development of this tool has now come to an end. It has several limitations, especially under newer Windows versions (it lacks correct support for hard links, compression attribute, junction points, etc) and it does not work at all under Windows NT version prior to 4.0. I recommend all users of this tool to use the new strarc instead. If you previously typed xcopynt d:\dir\ you may now use strarc and type strarc -c | strarc -x -d:d:\dir\ instead.
