move files to archive on ftp server after download


on my ftp server i have a "current" folder and an "archive" folder.

i've successfully set up the smartFTP transfer queue to pull down from the "current" folder on a regular basis, but once these are downloaded i want them to move to the archive folder.

this means they would still be available for future ftp download from my archive, but would mean the transfer is only bringing down (and checking) new files.

anyone know how i might do this. thanks in advance.
