[xwiki-users] Filesystem Attachment Store Porter Extension missing

I need to migrate a Wiki in Filesystem attachment Store mode because I have an existing wiki in which I need to import a big XAR file (>130MB) The procedure is explained here http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Attachments "If you already have a wiki and want to take advantage of the Filesystem Attachment Store, you should use the Filesystem Attachment Porter to move your existing attachments onto the filesystem. " but the script seem to have been removed a few days/weeks ago ... http://extensions.xwiki.org/xwiki/bin/view/Extension/Filesystem+Attachment+P... How can I move from DB to FS ? Regards,
