Simply point the integral folder manager at the top level folder that either contains your tiffs, or contains many levels of subfolders that in turn contain tiffs, and then point the output folder manager at your destination top level folder and superfast Tiff2PDF will convert every tiff file it finds to PDF and will replicate the entire input folder structure in the top level output folder.
Get SuperFAST Tiff2PDF and give it a try to see just how useful it can actually be for creating PDFs out of TIFF images!
