Hi,
The best way to handle this scenario is to use the default
RadAsyncUpload configuration. It firsts upload files into the
temporary folder and then on postback (clicking Save button) moves uploaded files from temporary to the target folder. Finally, all processed temporary files are deleted. Rest of the files that are not processed are cleared automatically after a set amount of time defined by the
TemporaryFileExpiration property. Default value is 4 hours.
