Unable to see files and folders in my pen drive

External hardware devices such as pen drives are widely used for easy storage and transfer of files or folders. Sometimes users may not be able to see files or folders stored on pen drives. This be down to several reasons, the most common being that all files and folders are in the hidden mode. If the storage device doesn't have this setting enabled, it could be due to undetected malware. Users may need to remove the autorun files first and then proceed with removing the infected files using a recommended anti-malware. 


Issue
I can't see the files and folders in my pen drive after scanning with "Advanced Options - clean files" with nod antivirus software. The files are not in hidden mode and I know they are on the pen drive as I can tell from looking in "properties". How can I fix this problem? 

1. Click on "Start" --> Run --> then type cmd and click on OK. 
2. Assuming your pendrive is G, enter the following command: attrib -h -r -s /s /d g:\*.* 
3. You can copy the above command then right click in the Command Prompt and paste it.
4. NB: Replace the letter g with your flash drive letter. 
5. Now check for your files in the pen drive.
