I transfered raw+jpeg files from my camera to ipad using camera connection kit.
I try to backup these files on my macbook using your app but only the jpeg files are transferred. raw files are lost ?!
i dont find a way to backup raw files, reading this discussion it should work.

inof: my camera is a panasonic and raw files have the .rw2 extension.

Thx for advices, however your app is great
