I want to look into a folder to see if there are any folders within it. If there are, I need to check inside each folder to see if it contains a .pdf file

So

If /myserver/myfolder/
contains a folder AND that folder conatins a .pdf file
do X
Else
do Z

I may have multiple folders and multiple .pdf files under myfolder. I don't know ahead of time what the folder should be called to do a test. I don't care about the folder name. I don't know what the pdf should be named ahead of time to do a test either. I just care that something ending in .pdf is in the folder under myfolder.
