Dispatch special characters

Hi forum

I have a lot of files named something like "Product name M16(2.0) some additional text" where (2.0) is the pitch of a standard M16 thread. Now, i need to add an extra 0 to these files and needed to find the string location for ".0)" but that would result in value that looks like Find(%NameOfSelectedFile%, .0)) where PDM ignores the last of the two end parenthesis. So how do i find a value like ".0)" in dispatch or any other special characters for that matter?
