Delphi DLL

Rename or Move a Remote FTP File

Demonstrates the Chilkat Ftp2.RenameRemoteFile method, which renames or moves a remote file or directory using the FTP RNFR/RNTO sequence. The first argument is the existing path and the second is the new path.

Background: Rename and move are the same RNFR/RNTO operation: changing only the final path component renames in place, while including directory components in the new path relocates the item within the same server. It is a metadata operation, so even a large file moves instantly — but both paths must be on the same server, and moving onto an existing target may fail depending on the server.
