ALFTP is an FTP client and personal FTP server utility from ESTsoft for Microsoft Windows. It is part of ESTsoft's ALTools product family.
While it has been available in Korean since 2000 as freeware (commercialized in 2002 for government and corporate use), it was first made available in English in 2004, and has since been made available in over ten languages. Translations for ALFTP are provided by members of the ALTools user community.
The software received positive reviews in South Korea for its simplicity, and for having a Korean language interface, illustrating the importance of localization for software.
