All the folders in USB drive are hidden. But Files are visible. How to make folder visible?

Folder Options -> 'Show hidden files and folders' already checked. Both 'hide extn for known file types' and 'Hide protected Operating System Files(Recommended)' are unchecked. Only when they are unchecked, the folders are visible but are greyed out like hidden. When I right click and check attribute, readonly and archive are enabled but hidden attribute is checked and disabled. When new folder was created, it automatically changed to hidden. I have run antivirus software and removed 3 viruses. Now am able to create folder properly. It is not hidden but old folders hidden attribute is still disabled. This happens to folders in USB drive only. Please help.

Sounds like some weird inheritance or system protection. But you can try the old attrib.exe program.So, suppose your USB drive is drive E. Start... Run... cmd(this opens a DOS box) cd e:(this switches to the USB drive) cd\(this switches to the root dir of the E: drive) attrib -h . /s /d(this flips off the hidden flag for every file and folder on the drive. You may need admin rights.)If you get some Access Denied error, then the OS (or a virus) is preventing you from flipping the flag.To check things, use "attrib /s /d" to get a dump of all files and folders attributes.--N.
