Most commonly virus infected computer, laptop or pen drive didn't shows your files. Recently I had 3 GB data in my pen drive but when I used pen drive to other computer it didn't show the data, can you believe that a 3 GB data has not showing in pen drive but when I checked drive space it showed a 3GB used space, i tried to option "show hidden files" but it didn't work. At last I find the new trick to do this.
1. Open your drive (computer or pen drive).
2. Click on "Search location" top right side
3. Type * and wait it will show your all files
4. Now you can use your file as normally.
