auto cad pdf launcher

we recently had a program written that would allow us the ability from the inventory inq. screen to launch to a directory that contains the files of our drawings from our auto cad files. this program which was written can not seem to travel down into sub directories to locate an actual pdf file? Can Sage actually be programed to look through sub directories? Or do we really need to store all pdf files in one location?

 

Some confusion on this matter right now.
