| You have a source local (or remote) folder, where new files are being added by some external process. You want to make sure that these files gets regularly transferred to remote (or local) folder. And you want to remove the source local (or remote) files once they are safely transferred. | You have a source local (or remote) folder, where new files are being added by some external process.

| + | A simple way to implement this is using both ''-delete'' and ''-neweronly'' switches of the ''[[scriptcommand_put|put]]'' (or ''[[scriptcommand_get|get]]'') command | ||

| + | If you need more control (like if you want to delete the files only after all of them are transferred successfully), you can implement this easily using [[library|WinSCP .NET assembly]]. See example [[library_example_delete_after_successful_download|*]]. | ||
| - | Perform the synchronization using ''[[script_commands#synchronize|synchronize]]'' command. Make sure the script generates [[logging_xml|XML log file]]. You can then [[logging_xml#parse|parse]] the log file to enumerate files than got successfully transferred and use the list to generate script to delete the source copies. | + | If you do not want to use .NET assembly: Perform the synchronization using ''[[scriptcommand_synchronize|synchronize]]'' command. Make sure the script generates [[logging_xml|XML log file]]. You can then [[logging_xml#parse|parse]] the log file to enumerate files that got successfully transferred, and use the list, to generate script to delete the source copies. |
