I use android. Recently I've found a problem.. I can see all the files and folders in my mobile phone.. But when I connect it to my pc to copy the files or folders to the pc I find that The folder is empty. But the size is 1.7GB. I can't see the files in my phone connecting with the pc. I check that the hidden files are visible in my pc. I am using Windows 7 ultimate..
Since Android 4.0, the connection standard that is used to connect your phone to your computer is MTP. To be able to see the files on your mobile from your computer when they are connected you will need to make sure you have the correct USB driver for your phone and also that the phone is unlocked.
