Add a new file extension

File extensions are necessary to open files with the right program. This article explains how to add a new file extension in the data base.

1. Open UBIK^® Studio and connect to database.
   In the Class Browser switch to the Content view.
   
   
2. Add a SelectiveItem in Admin mode
   Now browse to {System.List} in the Class Browser and open the MetaClass SELECTIVEITEM in the Bulk Editor (via Drag & Drop).
   
   
   Every row in the Bulk Editor is shown greyed and can´t be edited, because the MetaClass SELECTIVEITEM is a system MetaClass. So we need to enable the Admin mode.
   
   
   After enabling the Admin mode you can add a new row for your file extension.
   
3. Add your new file extension to the selective list
   Open the SELECTIVELIST MetaClass and connect the objects called FILETYPES with the Relation Editor to add your new file extension via drag & drop.
   
   
   
   

   Please do not forget the save button.
