Managing Cache (CATIA V5)
Windchill Workgroup Manager cache is a local repository for third-party CAD applications contained in a specific workspace, and is used only when uploading or downloading files to and from the server. Using cache improves performance because Windchill Workgroup Manager only downloads files if the content on the server is more recent than the content in the cache; and only uploads files when you direct it to do so.
By default, when you register Windchill servers and authoring applications, a .ws directory is created for cache. It is located under your user profile on your local computer. For every server location listed in the .ws directory, there are subdirectories for each workspace, and within each workspace subdirectory, there are subdirectories for each authoring application that is registered to that server.

Working directly in cache is discouraged so that data is not accidentally corrupted. To help avoid directly working in cache, a component on the client called the Workspace Local Directory (WLD), is available. It is recommended you use this component, rather than browsing to or saving directly to the caches from the CAD application. Sample default locations for the Workspace Local Directory (WLD)are provided below.

The cache location is defined by the environment variable PTC_WF_ROOT, which is the client connector cache. This is where all Windchill Workgroup Manager related client side information is stored. If the environment variable is not explicitly defined, the default location is the home directory of the Windchill user.
By default, cache is not shared between Windchill Workgroup Manager and Creo Elements/Pro 5.0.
If you are planning to run the Windchill Workgroup Manager and Creo Elements/Pro 5.0 on the same system and also want to have the cache residing in a non-default location, you must explicitly set the cache PTC_WF_ROOT for both these applications to different locations. For example, one method of achieving this is to create a start-up batch file for each application that defines the PTC_WF_ROOT environment variable cache location and then start the program.
The default locations for the Windchill Workgroup Manager and Creo Elements/Pro 5.0 cache, and Workspace Local Directory (WLD) locations, are as follows:
• Cache location for Creo Elements/Pro 5.0—%APPDATA%\PTC\Creo Elements Direct Modeling <version>\<version>\.wf
• Cache location for Windchill Workgroup Manager—%APPDATA%\PTC\Creo Elements Direct Modeling <version>\<version>\.wwgm
• Workspace Local Directory location for Creo Elements/Pro 5.0—%USERPROFILE%\.wf
• Workspace Local Directory location for CAD application—%USERPROFILE%\.wwgm

The Workspace Local Directory (WLD) no longer creates application-specific subfolders for each authoring application. All primary content files reside in the WLD folder without application sub-folders. Secondary content (attachments) is placed in a sub-folder. As a consequence of the new arrangement, during upgrade, an undo checkout must be performed on all workspace objects (not necessary when upgrading to Windchill 10.0). Administrators can move the content of any existing authoring application subfolders to the top-level WLD and delete the application specific subfolders.

Although it is not recommended you directly access the .ws directory; there are certain PDM actions that require you to select from it. For example, Open queries the CAD application subdirectory in the .ws directory so you can select the document you want to open. If desired, the location of the .ws directory can be changed by setting the PTC_WLD_ROOT environment variable to the required location.
Cache is managed from the Cache tab on the Server Management window ( > ). This window describes your workspace local directory/managing directory location, cache space used (in MB), and available disk space. There is also an option to clear the cache. The following graphic shows the Cache tab window.
This information is also displayed on the Cache Management window.
Select Cache Tools on the Cache tab to access the Cache Management window. The Cache Management window provides the following:
• Workspace local directory location of the active workspace for the primary server
• Cache location and usage. You can use the PTC_WF_ROOT environment variable to specify a different cache location.
• Path to the .ws directory
• Cache limit. The target cache limit can be set in the wgmclient.ini file entry cache.size, or by setting the environment variable dm_cache_limit
• Amount of utilized disk space
• The Clear button clears all cache in the inactive workspace. To selectively clear cache locations, click Cache Tools to access the Cache Management window.
Participant Management
Windchill uses the term "participant" to mean a user, group, or organization, or any combination of users, groups, and organizations. For optimal usability and security, participants must have unique user names.
You can use the Participant Management utility to add or manage participants.
For more information, see Working with Participants.
