Uploaded File Dissapears after SFTP in MInutes

Good Day

After using WinSCP 5.13 and uploading file on to FTP server using Microsoft SSIS using a script task, the file is successfully uploaded, however about 5 minutes the file disappears and sometimes a see a sample.zip.hash file in its place.

Any ideas

Thanks

That hardly has anything to do with WinSCP.
It's a behavior of your SFTP server. Contact your server administrator.
