Event/Trigger in server code when a new file was created by client

[e012345678]

Is there some way to get an event/trigger (or even by polling) when a new file was created by a client (especially by a specific user)? For instance I want the server to create a file test2.txt and send an email with uploaded file as attachment when user ABC uploaded test_*.txt. I understand the custom actions needs to be implemented but can the FTP server give the event/trigger.

1. The IUnixFileSystem interface has a CreateAsync method that is called to add a file to the FTP server. You can override this method.
2. You should be able to get information about the user using IFtpConnectionAccessor. You must inject it into your instance of IUnixFileSystem and check ftpConnectionAccessor.FtpConnection.Features.Get<IAuthorizationInformationFeature>()?.FtpUser.
