I implementet a file sender adapter with FTP protocol. There is a problem: the sender processes the files even if they're in use by another application.
I.E. If another application put files (via ftp) in the sender work directory (that is on ftp), the sender processes those files before their transfer is completed.
I don't want that this sender in a communication channel in PI 7.1, imports files in the system when they aren't completed yet.
There are some ways to block sender before it processes incompleted files (in an ftp)?
