untar in SmartFTP

I have downloaded a file filename.tar.gz. After I upload the file, how can I untar it within SmartFTP?

Thanks for any help!

You can't you need winrar or powerarchiever for that.

or in case of a unix-like ftp server which supports shell access, connect via telnet / ssh and extract the archive from the shell command line.

Thanks! I downloaded PowerArchiever as I do not have shell access.

THANKS FOR THE HELP!!
