While using Recognition Server 4 (build, during the verification stage, I see a lot of disk writes in locations like:



These occur on the drive where Recognition Server is installed, but I want to change the location to a different drive (faster, higher endurance), where I have temporary folders.  I don't see an option in Configuration.xml to change this.  How can I change the locations of the above folders, so the writes are happening on a different drive?

Please see the "ABBYY Recognition Server 4 > Appendix>Configuration File" article in the Recognition Server Help. The 3rd row of the code sample contains  <TempFolder> element: <TempFolder>C:\ProgramData\ABBYY Recognition Server 4.0\RS4WF</TempFolder>

<TempFolder> is for changing location of temp files of Recognition Server not of Verification Station.

For Verification Station there are two ways:

via Hard-link:

* delete folder ...\AppData\Local\Temp\4.00.OcrTechnology.3
* create instead hardlink with name 
4.00.OcrTechnology.3 that refers to desired location
= All temp files of 
Verification Station will be created on another location

via debug setting in windows registry:

* create key HKEY_CURRENT_USER\SOFTWARE\ABBYY\RecognitionServer\4.0\VerificationStation\Shell\Final_Debug
* add string value with name UntitledBatchFolder and specify desired location in it

Almost all (including 
Untitled.FR11.***) temp files of Verification Station will be created on another location

Don't forget to repeat these steps on all Verification Stations and for all user account's on it.

Thanks very much!  I used the debug setting in the registry, as you suggested, and it worked.
