Some times our Pen drive data not showing , means in pen drive properties we see the space occupy but when we open it,
it is blank or not showing all the Data.Same happen with the memory card also. Memory card has the data but not showing to us.
In that case we have the data in our pen drive or memory card but don’t have access to the folders or file. This is because of virus or some times files are hidden by a virus or user.So unhide your files from windows .
Follow some simple steps as i mentioned below to resolve the isssue.
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 H:
Enter this command.
attrib -h -r -s /s /d h:\*.* --> Press Enter
You can copy the above command --> Right-click in the Command Prompt and
Note : Replace the letter g with your pen drive letter.
Now check your pen drive for the files.
