256986 Description of the Microsoft Windows Registry



SUMMARY
A Windows 2000-based computer running Terminal Services creates, by default, a temporary folder under the %TEMP% folder for each client session. The name of this temporary folder is based on the hexadecimal representation of the session ID. Also, the creation of this temporary folder can be controlled by using either of the following methods:
 * Flattemp.exe Tool
 * Terminal Services Configuration Tool

This article discusses how to change temporary folder configuration, and also provides additional information about registry locations that store the temporary folder configuration information.



MORE INFORMATION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To modify temporary folder configuration, use either of the following methods:

NOTE: To use per user temporary folders, you need to verify that both tools described in this article are configured to have this setting disabled. If either of these tools is configured to have this setting enabled, per user temporary folders do not work.

Method 1
Use the Flattemp.exe tool to enable or disable flat temporary folders, or to query configuration settings. The syntax for the Flattemp.exe tool is:

flattemp /enable - Enable flat temporary folders.

flattemp /disable - Disable flat temporary folders.

flattemp /query - Query current setting.

NOTE: The default setting is disable.

For example, an administrator may disable per session temporary folders by typing "flattemp /enable" (without the quotation marks) at a command prompt and then pressing ENTER. This results in all clients sharing the same %TEMP% folder.

Method 2
Use the Terminal Services configuration tool:
 * 1) Start the Terminal Services Configuration MMC snap-in.
 * 2) Click the Server Settings folder, and then double-click Use temporary folders per session.
 * 3) In the Use temporary folder per session dialog box, click the appropriate configuration option.

NOTE: The default setting is Yes.

Temporary folder settings are located in the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server

Terminal Services configuration tool settings are:

Value: PerSessionTempDir

Type: REG_DWORD

Data value: 0x1 (enabled, the default setting)

Flattemp.exe tool configuration settings are:

Value: FlatTempDir

Type: REG_SZ

Data value: 1 (enabled, the default setting)

NOTE: This registry value only exists if flat temporary folders are enabled. If it is disabled, the FlatTempDir value is not present.
