I need to know the folder where I can add some PDFs to Windows Phone 8.1 so they can be found by the Adobe Acrobat Reader app. I've placed a PDF in /phone/Documents and every other folder I can see. Adobe Reader still does not see the PDFs.
There are currently no PDFs in Adobe Reader's list, so I cannot search for existing filenames and see which folder it is in. There does not seem to be any way in Adobe Reader's interface to import PDFs. I just want to copy to the correct folder and have them listed for reading.
