B4J Question FTP app directory permissions ?

[RickV]

I tried the suggestion of using ftp server and copied the code into my server project to add the ftp server functionality as exactly as the demo example in https://www.b4x.com/android/forum/t...d-with-socket-and-asyncstreams.74320/#content

I have created a folder c:\data\ftp
FTPSer.BaseDir = IIf(xui.IsB4J, "c:\data\ftp", xui.DefaultFolder)
and crated a user - FTPSer.AddUser("zz", "zz")

Listen port set to 21 - FTPSer.SetPorts(21, 65500, 65535)

OS win 11.
direct file explorer to 192.168.1.240 (b4j server app)
My file explorer gives an error after successful login. attached image and the logs from the b4J app below.

I am wondering what permissions do I need to set? Any extras on the directory c:\data\ftp ?
I tried adding anom user.... and adding it to the user list in code too
This server app is a desktop application that does many tasks, user maintenance, device authorities, sms and paging etc so a widndows user is logged in at all times (admin).
B4J is in debug mode but get same result in release mode.

Waiting for debugger to connect...
