I am asking about that as I have chosen Hosting Linux and in the case of upload of hidden files, to delete them I need to send a specific request to the provider because the FTP client can not delete them.
in the more modern macs there is a new option to show the hidden files, now instead of a Terminal command you can use the shortcut Command+Shift+period sign. open the exported blocs folder or for that reson any other folder on your mac including the Machintosh HD and type the shortcut and if there are some hidden files, those will be visible. use the same shortcut to hide them again.
