If you use Actions to convert many files from PDF to other types of files (HTML, doc, txt) and choose a folder, if you have other types of files in that folder it will open them in acrobat and try to convert them, most of the time, I just want to convert only the pdf from that folder.

Also it would be nice to have a folder/subbfolder option because sometimes you want to convert the pdf in a subfolder sometimes you don't.
