I am a contractor working on a new system for detailing and estimating. Using adobe reader to view the many scanned pdf files, I have to open 8-10 windows because all the documents are seperate. Is reader capable of consolidating multiple files into one window with tabs? Or do I need another program that is capable of this? I can't find it, and have tried a few ways to no success, and am wondering if the file being viewed has to be written with multiple pages in order to view in in one window, and if so, what program I need to be able to combine a full set of plan drawings into one file to be viewed this way.
