How to validate that a file has been uploaded successfully??

We basically want to validate whether we have successfully uploaded the file before trying to rename it or place new completion file. For this below is purposing solution can we implement them in FTP/FTPS/SFTP

1) By comparing the sizes of files available locally and the one uploaded.
2) By validating the header & trailer of the uploaded file, if both are present only then we can be sure that file upload is successful.

IF there is another mechanism which can tell about the file uploaded successfully please share also.

Kindly update me as soon as possible.

Thanks,
Abid

For FTP and FTPS, edtFTPj/PRO supports automatic validation via 1) the CRC of the files (if the server supports XCRC, e.g. ), or 2) via the file size.

This is via the setTransferIntegrityCheck() method. This isn't available (yet) for SFTP.
