Delete or move files after upload
The only thing I am missing is an option to delete or move files to an backup folder after upload. I would use FTPbox to upload files that are being processed on the other server. Right now FTPbox would keep uploading the same files over and over.
Well...sync will do the job. But 1-way Upload should offer a delete of local file after upload or move processed uploads to a local backup folder with timestamp prefix.
