I'm trying to open and view 28 PDF files, but am unable to do so. I have recently upgraded my computer and am now using Windows 7 with 12 GB of RAM. On my older system I was able to open this many PDF files at once, but now I am not able to do so. I can selects and open about 10 PDF files, but when I choose more than that and right-click on the files I do not get an option to open the files. Any help is greatly appreciated.
Select 10 files and open the files, then select and open the next 10 files.
