The one I used is not very complicated.

\\.  match a dot; it is a meta-character so it needs to be escaped.
{2,} repeated at least 2 times, at most an undetermined number of times.
.*   any character (.) repeated zero or more times (*).
$    end of string.

All together now.

"\\.{2,}.*$"  matches at least 2 dots followed by anything until
               the end of the string.

The replacement for this is the empty string "", so what is matched is 

Hope this helps,
