How to make a notification by mail if a file appears in a folder on FTP?

Question

Mail server

I have a folder on the server, for example , one of the employees can put an important file there, which must be quickly picked up from there. But you need to know that the file appeared there, the best way is to send a message like alert to soap.
How to implement this please?

Answer 1

I use this script at home (tracks: deletion, addition, file changes), I set up an alert on a telegram chat

Answer 2

If the server is Windows, you can write a console or Windows service that will monitor the folder for changes. In .NET, for example, there is a FileSystemWatcher, to which you can hook an event handler to create or change a file. Accordingly, in this handler, implement sending a letter.
I am sure that this can be implemented using PowerShell, for example
