Auto_ftp.pl came to be because I wanted to make a ftp client daemon that could be loaded on a server. Once loaded it would watch a shared folder and ftp anything put into that folder to the remote ftp site.
It is a Cross-platform, easy to use GUI FTP client which supports ftp transportations, bookmarks management, multi-thread transportation, TLS/SSL secure file transporation, etc. The installation is extemely easy by one click. Standard version is free.
