Pader-Sync let me know that their little known applications for remote file transfer are now free for personal use. This brings FTP, SFTP, SMB, & WebDAV access to regular users and commercial users can pay the $18 or $30 license fee after their 30 day trial. The apps are sold separately for each protocol or all together in PaderSyncFM.
I have tried their apps before and while they are not as well rounded as the older and discontinued Rove Mobile file manager they are still pretty good. That is especially so when you are in a bind and need immediate access on the go.
