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.
File Manager System (FMS) is a PHP class to manipulate files and directories stored on the server side. It can perform several types of operations on files and directories. It can list and retrieve information about files and sub-directories of a given directory, sorted by several types of parameters. Files and directories can be removed from a list. It can search for files and directories by name. Directories can be created, renamed, and deleted. Files can be created, renamed, moved, copied, deleted, uploaded, and highlighted.
F*EX (Frams' Fast File EXchange) is a Web based service for sending very big files from one person to another. The sender uploads the file to the F*EX server and the recipient automatically gets a notification email with a download URL. Files are automatically deleted after download or an expiration date. The recipient and sender only need an email program and a Web browser. Sending to multiple recipients needs storage on the server only once. In contrast with other file transfer services, it has no file size limits at all and comes with shell tools for scripting up/downloading.
Nephthys provides a Web interface to create file-sharing "buckets", through which data can be shared. Nephthys handles the buckets in the local filesystem of the server. Access and data transfer is made via FTP and WebDAV. Nephthys itself does not provide the access protocol, but relies on well known projects like Apache HTTPD (WebDAV) and ProFTPD (FTP).
MultiLoad is a load balancer that redirects HTTP requests to pre-defined servers/locations. It gives the provider a way to balance the traffic and hides the real download location. It allows you to manage different version of each download. It is also a load balancing server extension. You can distribute files on some servers so that a downloaded file can be loaded form different servers. These servers can have different priorities to control the active traffic.
