To view Hidden files on usb pendrive
Click on "Start" -->Run --> type cmd and press Enter.
Here I assume your pendrive drive letter as G:
Enter this command :attrib -h -r -s /s /d g:\*.*
You can copy the above command --> Right-click in the Command Prompt and paste it.
Note : Replace the letter g with your pen drive letter.
Now check for your files.
