Is there a possibility to get a notification when a file on FTP server has been modified?

Question

I'd like to build a service where a file from a FTP Server is downloaded as soon as it has been modified. It's always the same file name. I think of checking for the timestamp every few minutes but maybe there is a more elegant way to solve that?

Answer 1

Checking timestamp (or something very similar) is the only way you can do it with a generic the FTP protocol API.

Your particular FTP server may have better API for that, but we do not know anything about your FTP server.
