Dynamic Archive Folder (based on date) on FTP server

Dear Experts,

I have some interface scenarios of XML -> IDoc.

I archive the XML file on the FTP server every time PI process the XML file to an archive folder. Can I dynamically archive the XML file to another sub folder which is named by the date.

For example, if today is March, 3rd 2014. The XML files will be archived to archive/20140303/file.xml

To achieve this, I realize I need a way to dynamically set the date subfolder.

Can we use the Run Operating System Command? Because I think the command will be run at the server which hosts the Adapter Engine instead of the FTP server.

Thank you,

Suwandi C.
