Use turbo client. It is the only ftp client i have been able to use to connect to the vita. Just want to let you know the client is kind of weird. If you want to place a file in a certain directory you have to been in that directory first then upload your file(s) onto the vita.I Still have a problem, i seem to only actually access FTP with this using filezilla. But i wish to do so by other means. I try using the ftp function on my Android using es file explorer, and it never works, it stuck at a loading screen but nothing happens. I am able to use FTP with my other devices exept the vita henkaku. So i dunno what the problem is, i wish for any help possible.
