I am relatively new to iPads and I have a problem with pdf files. I use itunes to transfer pdf files onto my ipad 4 and I have iBooks and PDF Expert installed so I can read the the pdf files. But I also want to be able to be able to save individual pages from the pdf file. My problem is this: when I transfer a pdf file onto my ipad, it shows up in iBooks but not in PDF Expert or in any of the file manager apps I have tried. In iBooks, I have the pdf files organized in different folders. Any help would be greatly appreciated.
