Access saved file in Titanium by USB

Hello folks!

I'd like to know how can I access the photos that I saved with my Titanium Android app using the USB cable to copy for my PC.

I tried using the Ti.Filesystem.externalStorageDirectory and the Ti.Filesystem.applicationDataDirectory but both saved the file in the device (I could see using the ES File Explorer app) but when the device is connected to computer the same folder is not visible to copy.
