How to Delete Files via FTP in a Script?

Sadly, there is no ncftpdelete or the like. But to remove files scripted via ftp from a windows machine, you can use the scripting feature of windows’ own ftp client.

First, create a text file called del.ftp with content like this:

delete dir/

Then run ftp -s:del.ftp. This will execute all the ftp commands in the file del.ftp.
