Hidden System Classes

[Martin Obongita]

Hi all,
In my Omnis Studio 10.22 library, for some reason I cannot seem to find the folder System Classes where #BFORMS,#COLORS,#DFORMS,#ICONS are created. How do I search for them? I could have moved them unawares to some other folder. If I copy and paste the classes from a different library, I'm told the classes already exist. I have tried to search using ctrl_shift_F but failed to find them.
Martin.
