Don't forget the context of my post, namely that I was replying to someone saying they were unsure of whether the wildcard is handled by the client or the server. I didn't mean to imply that MDEL was an FTP command, only that it "Looks like the server does [the wildcard expansion]."

And thanks for the fuller explanation that NLST is the method by which the wildcard expansion is passed off to the server. I was kind of wondering how the client managed to put in the prompts for each file if the server handled the expansion.
