Maybe it would be sufficient to have the 3rd party send the file as file.xxx and then on completion, they could rename it to be file.zip or whatever you agree it to be. That way you have to just test if the file exists to process it. You could just use simple filenames or have a loading directory that the file is then moved from by the 3rd party when the transfer completes.

Of course, this relies on the 3rd party process to send then rename the file.


If they are using a GUI, (e.g. Filezilla) then you could ask them to send a simple flag file after the data being transmitted. They would need to ensure that they have their queue limited to one transfer at a time, else they could get out of sequence. The flag file might need to be named something like file.zzz to ensure it follows the data file, but it is less satisfactory using a GUI because there are more risks of transferring the flag file early.



I hope that this helps,
Robin
