All folders in HD not seen

I have 3 folders in my external HD and only the “Public” folder is visible when I look for it in WinZip or 7-Zip.  I need to  backup the Primary Vault and Wanalift Office every week but they don’t show up.  Any help will be appreciated.  Thanks

Hello, I think you are in the wrong board.

What’s the drive that you have?
