Append Bytes to a Remote FTP File (BinData)

See more FTP Examples

Demonstrates the Chilkat Ftp2.AppendFileBd method, which appends the bytes in a BinData to a remote file. The first argument is the remote filename and the second is the BinData. No conversion is performed.

Background: The binary append: add in-memory bytes to the end of a remote file without an intermediate local file and without any encoding or line-ending translation. It is the right choice for growing a binary file — concatenating captured data, for instance — where exact bytes matter.
