How to open files copied to android file system using Adobe pdf reader I have copied two dozen pdf's to the DCIM on the Android. How do I access them?

The Adobe Reader offers the following options:


My Documents - which points to a directory underneath the Adobe Reader and does not offer any way to configure (no File Open dialog)
Local - which only has one file "Getting Started.pdf"
Document Cloud
DropBox


So .. where is the standard File Open dialog to allow navigation to the  directory containing the copied pdf's?   This is an 6.0.1 Android device.

Update  I also copied the files to the Android/data/com.adobe.reader/files/Downloads directory (where the "Getting Started.pdf" lives).  They still do not show up.
The files that I copied over did eventually show up: after several minutes.  The files are showing up now in both the DCIM, Downloads and the Android/data/com.adobe.reader/files/Downloads directories. 

It is not clear why the delay .. Simply closing and re-opening the Acrobat Reader did not solve it.
