Retrieving Components from a Library
If you have a library in Windchill PDMLink that is a frequent source for components, a best practice is to set the configuration option pro_library_dir to point to that library as your default directory. Do this by setting the value of the config option to the path to the library, for example: pro_library_dir = <Windchill PDMLink server URL>\...\<library folder name>.
* 
The server URL is a "wt.pub://..." URL, not a codebase URL. An easy way to specify the config option value is to click Browse in the Options window to present the Select Directory window. When you navigate to and select your library, its path is entered in the Value field of the Options window. Then, clicking Add/Change assigns your selected path to the value of pro_library_dir.
Once you have assigned the path of your chosen library to pro_library_dir, you can navigate directly to your library. You choose the Pro/Library option from the Look In list in the File > Open window.
