Undelete Tips and Tricks - Setting up "versioning" for new file types

by Michael 19. June 2009 08:47

As a filter driver, Undelete captures everything (except those files/file types explicitly excluded). One of the advanced features of Undelete is the ability to organize previous versions of Microsoft office files into a common recovery location and remove all the wacky characters (~$, .wrl, etc...) normally associated with temp and older iterations of these files. This feature, called "versioning", supports a very intuitive method to easily locate, preview, and recover these previous versions (ex. Microsoft Word document, Excel Spreadsheet, etc.) which may have been overwritten. The feature is nicely integrated with Windows Explorer so you can easily right-click a file and select to view the versions.

We heavily test and officially support the predefined files listed: .doc, .docx, .dot, .htm, .html, .mht, .mhtml, .pot, .pps, .ppt, .pptx, .rft, .txt, .xls, .xlt, .xml; however a user may want to turn on this feature for another file type other than the default provided types. The data below will show you how to add other types, by file extensions. Please note this is a use-at-your-own-risk trick, and involves editing the Windows registry. And, also note that this workaround may not work correctly for all applications due to the manner in which some applications save their files.


For example, you may work at a design company and use AutoCAD and would like to turn on versioning for your CAD files. AutoCAD saves files with an extension of .dwg.

Again, to perform this workaround, you will need to edit the registry. Please note that an incorrect entry in the registry could damage your operating system and make your computer so it will not boot. Follow the instructions below to perform this workaround. 

To start regedit, select Start – Run and enter: regedit               

Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Diskeeper Corporation\Undelete\FRBin and edit the VersioningExtension key to add the file type which you want to use versioning on. Following is a screen capture of the registry key.   

Go to HKEY_LOCAL_MACHINE\SOFTWARE\Diskeeper Corporation\Undelete\FRBin and edit the VersioningExtension key to add your file extension followed by OK.  (For the AutoCAD example, you would add .dwg which is entered above.) Once this is complete, exit regedit and restart your computer for the changes you entered to take affect.

V-locity is here!

by Michael 16. June 2009 06:00

The new virtual platform disk optimizer for Hyper-V platforms is now available for sale and as trialware.

V-locity with InvisiTasking technology installs on both the Windows Server 2008 OS that is running the virtual host and all Windows virtual machines (guests). Each component optimizes its respective Windows OS and performs defragmentation of files and consolidation of free space. This minimizes unnecessary I/O passed from the OS to the disk subsystem and aligns data on the drives for optimal access.

With the proprietary InvisiTasking, V-locity will automatically and invisibly defragment files and consolidate free space on every Windows system it is installed, eliminating unnecessary and excess I/O to restore system performance and reliability for the entire platform. At the same time, V-locity provides a tool to analyze and compact wasted virtual disk space (dynamic disks).

In accordance with most virtualization software products, pricing for V-locity is "per CPU-core" (similar to the traditional per-socket) rather than per operating system. This provides users a fixed cost for their optimization solutions, and makes licensing much easier and more predictable as they 'grow' those platforms.

Future versions are already in the works, including support for VMware's enterprise solutions.



Techworld interviews Diskeeper Corp exec about new technology

by Michael 15. June 2009 06:30

A while back we undertook some interesting research projects. We built some high-tech tools to collect data about Windows behavior during the boot process. After analyzing that data, we realized we had a fantastic opportunity to dramatically improve system boot up for common Windows desktop platforms.

Techworld recently broke the story. You can read about it here.

You'll hear more about this new solution in the coming months as it hits the streets in popular laptop and desktop systems.
