Finding Certain Letters

Hey guys,

Sorry for the vague topic, I initially had a few queries but managed to find a solution.

I'm looking for a way to filter single characters that have a "." (period) immediately after them.

Does anyone know of the syntax?

Many thanks.

try
%_filename% MATCHES ^\d+&

and
%field% MATCHES ..
with %field% is the proper name for the field, e.g. %title%

Maybe something like this ...

Filter expression: "%_FILENAME%" MATCHES "<\S."
... or ...
Filter expression: TITLE MATCHES "<\S."
