@mani1304 , can you try to change the encoding and see that the issue exists?

Thanks but currently we haven't checked in the Filename encoding in the tFTP component and this only fails sometimes in a day and runs every 30 minutes. Should I checked that and what should be the encoding(ISO-8859-15 or UTF-8 or custom), it's SFTPing .pdf and .xml files created by below code.

byte[] decoded = Base64.decodeBase64(input_row.Body);
