PHFTP (PHP HTTP FTP) is a simple and fast Web FTP application. You can upload, download and administer files on FTP servers without a local FTP client, even if you are behind firewalls and proxies. The only thing you need is a Web browser HTTP(S) connection. If you can browse the Internet at your workplace, you can now also establish a FTP connection to any FTP server your PHFTP installation server can connect to.
aria2 is a utility for downloading files. The supported protocols are HTTP(S), FTP, BitTorrent, and Metalink. It has a powerful segmented downloading ability, downloading a file from multiple sources and multiple protocols and utilizing your download bandwidth to the maximum. It supports downloading a file from HTTP(S)/FTP and BitTorrent at the same time, while the data downloaded from HTTP(S)/FTP is uploaded to the BitTorrent swarm. Using Metalink's chunk checksums, aria2 automatically validates chunks of data while downloading a file like BitTorrent.
