Filter for Path & Filename exceeding Windows limit (260?)

I am trying to implement a filter that displays only files with a combined path and filename length exceeding the maximum allowed by Windows 10. I think it's 260 characters.
This is what I have tried, but it doesn't work.

$Len(%_folderpath%&%_filename%) GREATER 260

Any Help would be much appreciated.


"$Len(%_folderpath%%_filename%)" GREATER 255

Awsome! Works perfectly.
Thanks very much for the quick response.
