Easy way of procesing files using sender File/FTP adapter

Question

Hi experts,
In order to process files with a sender file adapter I am interested in avoiding processing non completed files. I mean files that are still being sent. My provider send an .XML file and when the sending is completed a .CTL file with the same name (and diferent extension).
So, my question is, wich  of the nexts is the best?
-Implement an adapter module who recognizes the .ctl and then processes the XML file. -> Is there any standar module doing already that?
-Use adapter standart parametrization: Run operating System Command Before/After Message Processing, some advanced parameter?
-Doing nothing, PI only processes completed files (possible??), or if it processes a non completed you can retry.
-Other
Points for the best/easiest solution.

Gonzalo

Hi Gonzalao,
>>Implement an adapter module who recognizes the .ctl and then processes the XML file. -> Is there any standar module doing already that?
No there is no such standard module available in PI
>>Use adapter standart parametrization: Run operating System Command Before/After Message Processing, some advanced parameter?
Again this is not possible as only after reading a file it will execute OS commands
>>Doing nothing, PI only processes completed files (possible??), or if it processes a non completed you can retry.
No you can' take this risk (unless there is a OS lock on the file which is being written)
>>Other
so i will go for other solution like:
A batch program which will check whether a ctl file exists and if it is found then it will ove the .xml file to one folder (where pi is polling) and deletes the read ctl file.
This batch code will be made to run for say every 5 sec or depending on the frequency of the interface
