how to protect usb

Check whether files are not in hidden mode.

Click on "Start" --> In search box, type cmd and press "Enter".

"Command Prompt" will be opened.

Here I assume your pen 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 : Don't forget to replace the letter g with your pen drive letter.

Now press "Enter".

Now check for your files in your pen drive.

Good Luck.
