Enable ftp access for Windows users. zFTPServer handles Windows or Active directory authentication automatically without the need to manually import users and sync user data. zFTPServer can also override and complement user data, offering powerful, simplified management, and superior ease of use.

Have zFTPServer notify users or initiate actions when events occur using powerful scripting facilities! This extension allows zFTPServer to enforce user scriptable rules and policies such as virus checks on uploaded files, automatically transform between file formats, and to send notifications about special events.

Have zFTPServer react to events before they happen! With this extension you can specify before-scripts that limits access based on date/time, downloaded files or even information stored in external databases. Together with "Reactive" you have a full-fledged Integration Server. Your imagination is the limit!

Schedule server activity to idle time when you are away from the computer. Speed Scheduler allows administrators to throttle upload and download speeds limits based on rule sets and time constraints. Rules can of cource be ignored for local network access.
