The file manager function allows you to take full control of your Web site's files. It is a safe alternative to full shell access for sophisticated users. You can copy, move, delete, rename and edit files, create and remove directories, change file permissions and upload files from your local computer to the server. File manager is best used to manipulate files that have been previously uploaded to your Web site. To upload more than one file at a time, an FTP client is generally more efficient.
