You’re welcome. 
e.Name is only a shortcut for the Element.Name node.
Most nodes in Python work in Auto lacing with a single element and with a list of elements but require Longest lacing for list of lists because the script is a little more complicated to write.
Adding to the flow capabilities, is it possible to run multiple filetype search without stressing out Dynamo too much? The original intention was to search for rvt, rfa and rte all at once using [".rvt",".rfa","*.rte"]; but even after longest lacing it doesn’t pan out result.
Another addition, if it’s possible, could the flow filter for multiple keywords (BKDI & CCC in my case). I tried them out but the list hierarchy piles up and the end result vagues out.
Thanks in advance,
Shaik
