If the remote server doesn't support this function, there's nothing you can do using SFTP. One thing you can try is to allow SFTP versions 4, 5, 6 (using Versions property of the component) but this is unlikely to help if the limitation is of the server.

You can connect using SSH (command channel) and issue a command "mv <old name> <new name>".

Thanks for your reply.
I have one more query

I need to check whether the file is in the copy process before moving it into different folder

for e.g. if a large file is getting copied into folder "A" and in the same time we are downloading or moving it into different folder.
What will happen??

Is there any way to check this beore downloading and moving file

*Maybe* you can do this via SSH, but this is very platform-specific, as you would need to install some custom application on the remote server which will do the check for you. SFTP obviously doesn't offer such functions.

This is specific to particular server software implementations (and to the way the file is accessed by third-party software) and is not related to the protocol itself.
