overwritten files in synchronize, instead change names

1. congratulations, app is great! :)

2. Now about my problem :)

I would like to create a script which will be not erase old files but change them names.
What I mean? Example

a) On HDD I have a file

b) script upload file to FTP

c) on HDD file.doc is change.

>> d) on FTP script change name from file.doc to file%date%.doc (or something like that)

e) than from HDD upload file.doc to FTP


Now, my script looks like this:

But script replace old files on FTP (delete old files, but it could just change names)

Is it possible to do something like this?

Thanks.

WinSCP cannot do this for you. This is a way too specific request.
You can use synchronize -preview mode with enabled XML logging. Then process the XML log to find a files to be replaced and rename them. Only after that, execute the actual synchronization.
