I'm launching file manager within the cpanel, but when I launch the file panel and click on the directory I want to go into, it doesn't show me any sub directories within the root...is this a bug?  I need to unzip a file on my server and I'm not sure how else to do this except with the file manager.

It is a bit confusing at first because clicking on the directory name itself is different that clicking on the icon on the left of the directory name. One of them send you into the directory, while another give you a list of choice on what you want to do with it (rename, edit, delete, unzip (for zip files), etc ...)
