Pen drive data show empty though data exists [Solved]

Problem: 
i am using transcend 4 gb pendrive.when I insert this pendrive in any computer,it shows the occupying space.but when I open it .it shows it is empty.

Solution:
Try this

Check if the files are not in hidden mode. 

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:\*.* --> Press Enter 

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 your pen drive for the files. 

Good Luck
