location / export email adress autocomplete list

[AC Question]

Hi All. I want to export all email adresses ever typed in my email app on my samsung galaxy tab 10.1 (android version 4.2.2). When I type in the first letter of the email adress, a list appears with all previously entered adresses which have that character(s) in it. I want to see/export the complete list of possible autocomplete email adresses. Or I want to know where android has stored these email adresses. I do not sync with google or anything, so the autocomplete email adresses (previously entered emailadresses) must be stored on the device somewhere right? I have googled a long time but cant seem to get the answer. Thanks in advance for the info. Regards, Frank.
