Thanks for your welcome.  I did find the folder Matt....osmdroid...contained lots of Chimani folders but not many files.
I deleted the folder and started again. This time I think I may have sussed it out. Files say they are downloaded
but not ALL of  them are, so I just download again and it picks up where it left off. Zoom in on the maps and when offline hey presto!
.....so far!   BTW, Chimani do maps and info for many of the US National Parks.    Thanks again for the comments.

Hello,  bought myself a nexus 7 and so far am very pleased...BUT...having a problem with Chimani offline maps.
They say they are downloaded and verified but don't exist in the Chimani map folders, and not available offline.
My Nexus spent 26 hours downloading Olympic Natl Park (there are a lot of files!) but.....nothing ! Same with three
other maps.
I expect to be told that I should post this somewhere else, but I'm VERY new to forums,........ and getting OLDER by the day!

Can anybody help?
