How do I change the file name when you send to the server?
Using PARAM NAME="template" but it also changes the name of the file where the transfer is interrupted.

Template is the correct parameter. I don't understand the issue about interrupted transfer?

I'm sorry I wrote wrong. What I mean is that we want to the file name has been added "_ok" after the upload to finish. Another person with access to the files on the ftp server needs to see whether the file has already been sent.

So you need an unique filename for each file to avoid overwrite?

Send a large file ftp. The owner ftp checks if the file is sent in its entirety - must see the file name added "OK". So my script after sending the entire file must be added to the name of "OK".

JDiskExplorer does not issue additional FTP request after upload except an optional chmod.
What you could do is use 'forward' parameter to run a server-side script (such as PHP) that will rename the remote file uploaded.
