unix - FTP Delete non empty directory

Question

I am connected to a Unix server and I am trying to, via FTP, delete the directory dir with several files in it. If I use

ftp> delete dir/*

I get

550 Wildcard is ambiguous.

When I use

ftp> prompt off
Interactive mode off.
ftp> mdelete dir/*

I still get

550 Wildcard is ambiguous.

When I try

ftp> glob
Globbing on.
ftp> mdelete dir

I'm prompted for every file.

How can I easily delete/empty-and-delete a directory without getting prompted for every file?

Answer 1

I got it to work in two steps, on a server with restricted access, no SFTP, only FTP through commandline.

Like this :

mdelete folder_name/*
rmdir folder_name
