Question

How do I change the location where the Processing Engine writes temp files (a.k.a, ADTemp)?

 

Answer

There are 2 places this setting should be changed.  The registry is where a Distributed Processing Engine (DPE) stores this value and the config file (application) is where a local Processing Engine (EP) stores it.  The attached script will help automate making changes to both.

Registry (eDiscovery, Summation, DPEs)

1. Open the registry by clicking Start >> Run >> regedit.

2. Open the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\AccessData\Products\Common.

3. Select the Common key and in the window pane on the right, right-click TempDir and select Modify...

4. Enter the exact path of the desired ADTemp folder and click OK.

 

Application (FTK, AD Lab, AD Enterprise)

1. Open the application (i.e., FTK, Lab, Enterprise) and sign in.

2. On the menu bar click Tools and select Preferences...

3. Click the ellipsis (...) and choose the desired folder.

4. Click OK

(Note: This saves the preferences to the file "C:\ProgramData\AccessData\Shared\sds\Preferences.xml")

 

Overview

A dedicated ADTemp folder on a fast disk with low fragmentation (i.e., SSD) will improve performance dramatically.  For more information on ADTemp, please see the articles below.

    Will this script work on DPE's? I cannot find the Preferences.xml file on the DPE, will changing the registry key do the trick?

    Either way is fine. DPEs don't typically have or need the Preferences.xml (which the script will create), but having it will not cause a problem.
