Link to Configuration Variable with Filtering (Harvested Folders)
A harvested folder displays models or saved views that are contained in a set of files. Using harvested folders, you can keep track of sheets, views, and drawing boundaries, because the folders are an up-to-date view of what is in the files. MicroStation generates the content of a harvested folder by searching for specified resources within a set of files. When resources are added, removed, or renamed, harvested folders can be refreshed to reflect the changes. Several pre-defined harvested folders are delivered with MicroStation, including folders to display sheet models and several types of saved views.
To create a harvested folder, create a Configuration Variable link by specifying a configuration variable and a resource filter. The configuration variable identifies the set of files to be searched. The resource filter identifies the type of resources to find within those files. A harvested folder can only show one type of resource. To track more than one resource, you need to create a separate folder for each type of resource.
Any configuration variable that identifies files or directories can be used to define a harvested folder. MS_DEF is such a commonly used configuration variable. If the configuration variable identifies a directory, then all files in the directory and its subdirectories are searched.
