for cpanel-based hosts that run php as your user account, it is usually easiest (and fastest) to extract and then rezip without a nested folder (zip the folders and files inside the extracted getsimple-ver folder) , locally, then upload and extract to the desired location on the server (usually public_html) using cpanel's web-based file manager.

It's best to not use cpanel and use a ftp program instead. Because some plugins (I18n Gallery, etc.) have their file + folder permissions set to 777. If you upload and unzip that will not change. While copying via ftp, ftp software changes the permissions to correct permission setting (if configured correctly).
