The metadata for a folder are stored in a XML
file called fileanchor.xml
You can simple add variables in the subtree
<METAARRAYS> .
Each new variable will be added to the search
tab in the GUI. (see examples in TEMLATE_FOLDER)
The search result can be opened in the filemanager
by clicking on the cover picture in the Result tab.
The application for the folder path result can be
set in the menue CONFIGURE->SET OPEN FOLDER
