Would you like to help out with the development of zFTPServer?
You can do so by running the experimental version of zFTPServer to help us collect additional information during testing, please follow the guide below!
Before we start, please note that this version is not intended for daily use and may cause issues during use.
1. Start out by confirming if you are running the 32 or 64 bit version of zFTPServer, then download the zFTPServer.exe and the zFTPServerAdmin.exe for your version here:
zFTPServer x64 – Unstable: 
zFTPServerAdmin x64 –Unstable: 
zFTPServer x32 – Unstable: 
zFTPServerAdmin x32 – Unstable: 
2. Now, stop your currently running zFTPServer service.
3. Replace the zFTPServer and zFTPServerAdmin.exe located inside your installation folder, usually C:\Program Files\zFTPServer\ with the files you just downloaded.
4. Start the zFTPServer service.
From now on the administration interface is web based and built into zFTPServer.exe. Simply point your browser to the default binding 8443 or specify your own in Settings.ini under the section "[HTTPS Admin bindings]".
