Thank you for your reply, tiny.
When I open the files and “save as” and switch to either .txt or .doc , then try to import into my N7, I get the message “sorry, cannot copy”.
I have imported the files into N7 when it's connected via USB. The files then have the .odt extension which is Open Office.
They open and are readable in the N7content when hooked up with USB.
When I try to open the same files on my Nexus, I get the message “no application available”.
I don't know how else to handle it....If you have any other suggestions, I will appreciate it very much.
