As I said, have your Tasks in Windows look in <your PDF directory> every <5-15 minutes> and create a list of filenames "dir *client*.pdf /s /b > FileList.txt" [note that this will overwrite itself the next time it runs] and then use a "for" command to process each line [= file found] in that list.

The "for" command is very powerful because you can specify what constitutes a 'break' between parts; 'space' is obvious, and 'period' means that the 'pdf' at the end is not cluttering up the last part of the name if you want to move that around...  just make sure that you include '.pdf' extension when you are doing your output filenames.

I  recommend keeping your original files & storing renamed *copies* where you want to use them, rather than renaming....  just in case.
