@Taifu Thank you! It's possibile to view the blocks of that operation? I'm a beginner..
I'm trying your sample app for files. If it is on the phone, and not emulated, it says the file does not exist when i try to copy.
This is from my app. When executed,it says error 2001, The file "file:///mnt/extSdCard..."could not be found on your device..
Etichetta1.testo contains the filename.mp3
