HpaFTPw Pro

HpaFTPw Pro is the Windows version of hpaftpd single-threaded ftp-daemon HpaFTPw Pro is running as Windows service and has the separate Control Panel for your convenience.

HpaFTPw is the Windows version of hpaftpd (single-threaded ftp-daemon for Unix). It is designed to run without threads and with low memory usage, so it's suitable for heavy network traffic with very many connections.
It work well with different GUI-based ftp-clients (FAR FTP-client, Total Commander, IExplorer, Konqueror(KDE browser), Opera etc).

The single-threaded philosophy makes it faster than most other FTP daemons and makes it very light on memory. Standard FTP servers create a thread for each new incoming connection, and then one or more child threads for each directory listing that connection requests. HpaFTPw does not need to create any additional threads after initialization.
