How to extract archiv

Sorry for stupid question but I can’t extract tar gz archive after downloading it to bplaced.
Befor when i’ve used different host I’ve connected via ssh and operate with archives. Here ssh it seems doesn’t support (or i am wrong?) and i cant open archive using ftp console only.
Help me please.

You do not get an SSH-account on bplaced, so you have to use a PHP-script, either a specific script just to extract the one file or install a complete PHP-filemanager that supports extraction of archives.
